Having the right boiler for your central heating system is extremely important for any size home but it is even more so important for the larger properties with 4-6 bedrooms, multiple radiators and numerous bathrooms. No one want’s cold water coming from their new boiler.

There are 3 different types of boilers on the market: Combi boilers which are also known as combination boilers, System boiler also known as a traditional boiler or the Regular boiler also known as heat only, or conventional boilers.

We will give you options and compare 2 models of each boiler to help you find the most suitable boiler for you.

Combi boilers are most suited to homes with 1 bathroom that don’t demand hot water and heating all in one go. For those that do have just 1 bathroom, a 25kW would be perfect for this size of the home if you were to get a new boiler for your central heating system.

System boilers, conventional boilers and Regular boilers are known to be efficient and reliable for a larger home that demands a large amount of heating and hot water for a number of baths and showers at once.

If you know which type of new boiler is most suited to your central heating you can jump to the most relevant section which will help you find the perfect manufacturer and model for your property..

Is a Combi Boiler OK for a Large House? Best boiler for a large 5 bedroom house Compare Boiler Quotes

A System or regular boiler would be more suited than a combi boiler for a larger home.

Here we have put the 2 most powerful Combi boilers head to head to help make your decision more straight forward: Vaillant EcoTEC Plus 938 vs Worcester Bosch Greenstar 38CDi Classic.

What is a Combi Boiler? Best boiler for a large 5 bedroom house Compare Boiler Quotes

Combination boilers living up to their name by offering both central heating and hot water on demand. They often need to live in a kitchen storage cupboard as they are small, compact and easy on the eye.

They heat water directly from the mains to provide instant hot water to the showers, baths and taps.

System and Regular boilers store the hot water in a cylinder heated by the boiler to be used as and when required.

For this reason, a Combi boiler would not be recommended for a larger home, sending water to more than 1 tap at a time will weaken the pressure and could eventually cause a breakdown.

Price

Comparing installation boiler quotes from heating engineers is as important as comparing different boiler models.

Each Gas Safe engineer will vary the installation price.

Warranty Best boiler for a large 5 bedroom house Compare Boiler Quotes

To keep the warranty valid always remember to have your annual service by a Gas Safe engineer, some brands insist you use an engineer who is on their register.

A standard 5-year warranty can be extended up to a further 10 years when installed by a Vaillant Advance installer.

The EcoTec may be slightly more expensive but in the long run, could be cheaper as it has a longer warranty therefore if any problems occur in the future you have the peace of mind that you would be covered.

Output

As a Combi boiler isn’t the recommended system for larger homes with multiple bathrooms, we’ve compared 2 powerful units, both coming in at 38kW.

Best System Boiler for a Large House: Vaillant vs Worcester Bosch

As said before a System boiler is highly worth considering if you live in a larger home due to how they store hot water in a tank. This allows hot water to be supplied to more than one tap at a time without changing the pressure.

We’ve compared 2 System boilers that you might want to consider installing: Vaillant EcoTEC Plus 637 vs Worcester Bosch Greenstar 35CDi Classic.

What is a System Boiler? Best boiler for a large 5 bedroom house Compare Boiler Quotes

A system boiler takes hot water directly from the mains like a Combi boiler but stores the hot water in a tank and heats the water on demand in the same way as a Regular boiler.

This method allows hot water to be delivered to more than one tap at a time without altering the pressure.

Price

Remember the price of the boiler doesn’t include the installation cost.

The EcoTEC Plus will probably have the more expensive price tag out of the System boilers, on average £200 more that the Greenstar 35CDi Classic.

Both of the above System boilers will heat your home effectively and efficiently as shown through their ErP A rating.

Ensure you have your boiler annually serviced by a Gas Safe registered engineer to help prevent any faults occurring, to reach the full life expectancy and to keep the warranty valid.

What is a Regular Boiler? Best boiler for a large 5 bedroom house Compare Boiler Quotes

Regular boilers are the oldest type of boiler on the market, you might have heard of them under a different name: Traditional, Conventional or Heat Only.

The same as System boilers, they require a hot water tank but the difference is they don’t take water directly from the mains. Instead, a cold water tank needs to be stored in the loft which delivers water down to the cylinder.

They might be the oldest type of boiler around but they are well known for being efficient and reliable.

They’re often well suited to older homes with original pipework which can’t cope with the strength of mains pressure. Best boiler for a large 5 bedroom house Compare Boiler Quotes

Price

There is a fairly large price difference between these 2 Regular boilers.

The Greenstar 40CDi is available with a smaller price tag.

In addition to the cost of the unit, don’t forget to take into consideration the cost of the installation which will be different from each installer.

To get the best deal possible on the installation, we recommend getting quotes from numerous installers and comparing them. Always use a Gas Safe registered engineer.

Don’t let the price make your mind up without finishing off the other comparisons.

Best Hot Water Cylinders for Large Homes Best boiler for a large 5 bedroom house Compare Boiler Quotes

If you live in a large home with multiple bathrooms and over 4 bedrooms then we highly recommend installing a System or Regular boiler.

Both of these boilers will require a hot water cylinder.

There are 2 different types of hot water cylinder: Vented and Unvented cylinders.

A vented cylinder requires a vent pipe or tank as the water expands when heated.

Unvented cylinders have built-in safety features such as an expansion unit at the top or an air bubble that is inserted at installation to cope with the excess.

Unvented take their water supply directly from the mains so there is no need for a cold water tank in the attic.

They can be installed pretty much anywhere in your home and provide a much stronger flow of water.

The system is completely sealed which helps to prevent contamination. This is because you don’t need a tank of water.

Knowing Which Size Cylinder you Need

Getting the correct size cylinder will help prevent wasting energy and will provide your property with enough hot water.

To give you a rough size guide: “For every person living in your home add 35-45 litres to the size.”

To get the perfect cylinder for your home, you should question a qualified installer for their advice.

For large properties with multiple bathrooms, you’ll be looking at a capacity of 300+ litres.
