For me, a 30kw combi is the best option for this. The manufacturer you choose should really be down to the engineer in my opinion. The boilers are basically all the same these days with nearly all the same working parts. The engineer will have a good relationship with his preferred brand and this will make things easier if you ever need to get a warranty call.

A common misconception people can make when thinking about a combi boiler is thinking that the more radiators they have in the house the bigger the boiler needs to be. NOT TRUE. The pump in any size combination boiler is the same size, It is the burner inside the boiler that changes. The size of your combi is determined by your incoming water flow rate. For an example if your water flow rate was 18 litres a minute and you fitted a 24 KW combi you would only ever get luke warm water. Why? Because the burner is not big enough to heat the desired amount of water.

“What is the best Combi for a 2-3 bedroom house?” This is a vague question and hard to give a 100% answer but a 2-3 bedroom house with 1 bathroom should normally require a boiler of 24-30kw. There are several variables to this which would need to be discussed and checked before I would normally recommend a specific boiler. Is the water pressure sufficient? What are the current flow rates at the hot/cold outlets? How many people occupy the property? How many bathrooms or room which require extra outlets? I would normally go for a Worcester or Vaillant 30kw boiler but will fit the best boiler at the budget of the customer. When recommending a boiler I believe in promoting the best after service and during my experience it has come from these brands. When looking at Combi boilers and sizing the output or Kw is linked to the hot water performance so the higher the output the higher the flow rates through the boiler and to the hot water outlets. If you like a large bath or a more powerful shower then a bigger output would suit but the existing pressure and flow would have to be available. Before recommending I would always visit the property and make my judgement on what is best for that customer.

We have found the most popular choice of combi boiler to be Baxi 630 for 2/3 bedroom houses. Baxi claim to have to have a 12.2 litres per min on hot water demand but the main factor is providing the mains water pressure to the property is of adequate pressure to begin with. Having fitted the Baxi duo-etc and Platinum combi boiler over the 10 years we have found them to be quite robust with little complaint if any at all. As a Baxi approved installer we decided to change to Baxi 630 as a preferred engineered choice based on the fact of its size as It can easily fit into a kitchen cupboard and is lighter than the duo-etc/Platinum combination boiler range. Also a big factor is the warranty is 7 years labour and parts with the 10 years option coming soon in Autumn 2019. Most combination boilers can come with the same warranties but we have found with little support and limited terms and conditions from the manufacturers but as with Baxi it’s usually no quibble putting its Baxi Approved engineers and customers a priority.

Benefits of combi boilers include: Save space in your home. Combining both a water heater and a central heating boiler into one unit greatly reduces the space required. Mains pressure water. Hot water is delivered through your taps and shower at mains level power, allowing you to enjoy high power showers. Lower costs.

Any 24kw to 28kw combination boiler should be sufficient for this size property. As long as the incoming mains pressure is checked prior to it’s installation. Combination boilers should not be fitted where there is poor incoming flow rate, they do not increase the water pressure. Please also bear in mind they will probably only give you a good flow rate to one standard bathroom at a time. Check that your installer has done his homework as per the manufacturers specifications before it’s fitted. Also consider how many radiators you have on your system and whether you may be adding any more or even adding an on suite etc before installation. Also make sure you also get the extended warranty and it’s fitted by a qualified Gas Safe Registered engineer.

The choice of boiler, mainly depends on the hot water requirements of the household. Some combination boilers will struggle with two high flowing showers running at the same time. Once this is done, the incoming mains pressure & flo rate should be checked. You can install a 12 ltr per minute boiler, but when you add the other cold water requirements of the property. You may need 20 ltrs entering the property. That done a 25 kilowatt boiler is usually ok, if the property has one bathroom.

The boiler would all depend upon what the hot water demand may be. You also have to look at the incoming cold main pressure and flow rate ( no point in having a boiler capable of giving you 15 litres a minute of hot water when you only have 11 litres a minute of incoming cold water) the brand of the boiler would depend of the budget of the customer. (My personal favourites are Ideal Vogues or the Baxi 600 series). For a three bed house, I would always opt for around a 30kw boiler. For plenty of hot water and would more than likely have enough left in it for any future extensions to the hot water demand.

You must consider the amount of bathrooms in the property and then calculate the size of the boiler. Combi boiler is sized mainly to the hot water and most 24kw boilers will heat a 2-3 bedroom house easily so sizing the boiler with a high flow rate is important in this case so in my opinion either a Vaillant combi boiler or an Atag depending on required flow rates.

In all honesty if a water main has adequate flow rate and pressure then any boiler sizes accordingly . Combi boilers are sized really for the hot water capability ie how much flow rate they produce . The heating side is generally irrelevant as a entry level 24 kw combi will be more than sufficient for heating most 2/4 bed house. You need to check flow rate and pressure , and how many hot outlets required then size accordingly . But in my opinion of make ? I would fit ATAG or Baxi

My personal choice would be an ideal logic max 30/35kw. My reason for this is I believe that the 10 year warranty is amazing. I know other manufacturers have offered similar warranty to this but the price says it all. For such a competitive priced long warranty boiler I believe the manufacturing side speaks for itself. Who would offer a warranty for 10 years if they thought it would break down. Other added factors which persuade me to this particular boiler it the magnetic filter that is included and the customer care at ideal. I had never fit an ideal boiler before a customer asked me and I can honestly say I was that impressed I have now fit hundreds (along with other brands) and keep going back to ideal. One boiler once had a problem and I phoned technical on a Friday evening. They couldn’t assist so passed it to their engineers. One arrived at 11am Saturday morning and fixed the fault.

Ok - so this question can be rather ambiguous without a survey of the property. But, generally we would recommend a 28kw boiler for the job. This will supply ample hot water and run the heating system very efficiently. When looking for a new boiler always find out how much warranty the boiler comes with from the manufacturer. If the manufacturer is prepared to give you a good warranty then they must have confidence in their appliance, this is a good rule of thumb. Still today some manufacturers offer 2, 3, 4 and even 5 year warranties.......Look for one that offers 7 years plus! Also....check the warranty offered....parts and labour, parts only? And how many hoops are they going to ask you to jump through? Main dealer service only or any Gas Safe Registered installer? We recommend the Alpha Evoke 28kw, complete with an out of the box Alpha warranty of 7 years ( can increase ) and only hoop you have to jump through is to have your boiler serviced by any gas safe registered installer.

In any situation it would be best to call on a time served engineer to conduct a site survey and answer a few questions regarding water usage and demands. In most cases in this type of property a 30kw boiler would give ample supply to meet the needs of a small family. There are many different manufacturers on the market and the choice is usually driven by budget. Worcester sit at the top of this at the most expensive, vaillant baxi sitting mid range and ideal at the lower end. Ideal seem to be a good option at the moment due to a long warranty.

With so many options available on the market the choice is endless.

Heating wise a 24kw boiler would be fine. If the property has more than 1 shower attached to the hot water system then I would recommend the intergas boiler. Due to it's different design no other wall hung boiler can compete with the flow rate. To get a better flow rate then you'll need a higher powered boiler. The same would apply if the property has a bath. If the property only has electric showers then a 24kw will do.

In the murky world of plumbing and heating there is never a straightforward answer! Some of the stipulations needed to decide on what boiler is best for the property are as follows. How many bathrooms are in the property? How many inhabitants are in the property is it a family is it a rental property does there need to be a couple of hot water draw off points running at the same time? What's the flow rate to the property all boilers have a certain flow rate design and can only give enough hot water as what is entering the property hrough the cold water tap usally or garden tap usally best place to measure the true flow rate from.e.g. less than 10 liters a minute then a 24Kw would suit bearing in mind that 10liters a minute hot water is all you'll recievd from your hot tap. If it's less than 13 liters a minute then 30kw boiler may be the right choice for you. The amount of radiators isn't a massive concern when choosing a combi boiler. Its all based on your hot water needs! Which is like a water lottery depending on your area. If you're looking for a new boiler to be installed in your property. I'd be more than happy to come round measure the flow rate in your property look at your living situation and recommend a boiler for you.

This unfortunately is not as easy as the question suggests. If you have a low flow rate ie litres per minute coming in off of your mains water say below 10 litres per minute then you may not even be able to have a combi boiler purely as they all have a minimum flow rate they work to effectively so that they can modulate correctly and be efficient or otherwise what's the point? Now bear in mind this is just a rough guide and there is more to it than this but say you had a flow rate of say around 11 lpm you could have around a 26kw combi boiler, then say you had around 16 lpm then you could have a combi boiler of around 30kw however this would probably only be suitable for 1 bathroom and 1 shower. If your flow rate was 18 to 20 lpm then you could go for a 40kw, depending on the manafacture most 40kw combi boilers can handle 2 bathrooms with showers depending on the size of the heat exchange within the boiler and the manafactures specification, however this isn't always garunteed. If you find that there isn't enough flow rate to your property to have a combi boiler don't despair as there are pumps on the market that will increase your flow rate to 12 lpm meaning you could then have a lower kw unit fitted. Alternatively if you have a massive flow rate and an incoming main of 3 bar or over with 2 or 3 bathrooms I would strongly recommend you have an unvented cylinder and system boiler.

MD Plumbing and Heating answered the question "What is the best combi boiler for a 2-3 bedroom house?"

Whether it’s a one bedroom flat or a 3 bedroom house, combi boilers are sized according to the mains water flow rate coming into your property. If you have a low mains water flow rate for example of 9 litres per minute, a 24kw combi will easily handle that to give you sufficient hot water. There would be no added benefit at all of putting in a big 35kw combi, all this would achieve is a bigger hole in your pocket! Both from the cost of the boiler and the new gas run that would most likely be needed. Most houses are so well insulated these days so they don’t have the heat loss they did in the old days, so a 3 bedroom house with 10 radiators would only need 10-15kw for the heating so again a 24kw would be more than big enough for the heating side. Always get a gas safe registered engineer round to quote as he/she will best advise what boiler is suitable for your property.

The best combi boiler for a two to three bedroom house will vary, I would go more by the way the occupants use their hot water. Generally, the hot water flow rate (litres per minute, at a given temperature rise) will depend on the kilowatt OUTPUT of the boiler. If a property only has one or two occupants with low water demand a 24 or 26 kWh model will suffice. If by contrast a family live there with large hot water demands and baths are needed quickly, then a 30-40 kWh model may be better suited. Bear in mind that the radiator requirement will almost always be met by the lower models as the radiators are not needing to be heated as quickly as tap water is.

The must suitable Combi boiler for any house depends upon the incoming mains pressure and flow rate. Any Combi boiler should be matched to the income mains so as to enable the correct hot water output. Any Combi boiler would be able to supply sufficient output to heat the central heating system in a 2-3 bedroom house but it would be a waste of money fitting a boiler that was capable of delivering 15 lpm if the incoming supply is only 10lpm.

Thoroughbuild UK Services Ltd answered the question "What is the best combi boiler for a 2-3 bedroom house?"

Probably a Potterton Gold 24 HE or a Baxi DuoTec 24 HE - These boilers are very efficient and the Baxi range are compact and they are very, very reliable. A 2 bedroom property with an average of 6-7 radiators would be fine with one of these boilers. On an average double panel size radiator the calculations are roughly 2 KW per radiator, and on a single rad they are roughly 1.5 KW. One of these boilers would be more than suitable. Also, take into consideration that every installer will recommend their own favourite brand to the consumer.
