Best Combi Boiler for a 3 Bedroom House

combi boiler diagram how it worksWhen looking for the best combi boiler for a 3 bedroom house, you have a fantastic range to choose from. The top of the pile for us at Clever Energy Boilers is the Worcester Bosch Greenstar 30i. This 30kW, wall-mounted combi boiler is branded a Best Buy by Which? Magazine in the publication’s annual boiler report. This takes into account the thoughts of both customers and installers, giving a great overall picture of how good this combi boiler is.

The Worcester Bosch Greenstar 30i is A-rated for both central heating and hot water and runs with a staggering 94% efficiency, making it a great model if you are looking to cut your energy bills. The low energy pump means your use of electricity is reduced too. It is also easy to use thanks to its simple interface, and is ideal for small or medium homes with one bathroom.

Whilst the Worcester Bosch Greenstar 30i may be the best combi boiler for a 3 bedroom house, the Vaillant ecoTEC Plus 832 is another great option.

You can find out more about both models in the best combi boiler reviews section.

It should be noted that these boiler suggestions are meant as a guide to the requirements for heating a 3 bedroom house. Of course, not all 3 bedroom houses are equal.

Best Combi Boiler for a 4 Bedroom House

Best Combi Boiler for a Larger House

In general the larger the size of the combi boiler, in terms of its kW output, the more suitable it is for a larger house. It is also worth bearing in mind that if you have more than two bathrooms, you might be better suited to a system boiler. Combi boilers take hot water straight from the mains and heat it up before sending it to the showers, baths and sinks. If there is too much demand, you might suffer from a reduced flow. System boilers store hot water so that it is immediately available and can handle large demand more easily.

For properties with up to two bathrooms, the best combi boiler for a larger house would be a model in the Worcester Bosch Greenstar Lifestyle range. These brand new combi boilers not only look modern and leek, but they also provide a powerful supply of heat and hot water. The range comes with models offering up to 50kW to keep your home toasty in an efficient and more environmentally friendly way.

The Worcester Bosch Greenstar Lifestyle range is compatible with smart controls, so you can keep on top of when your heating comes on and goes off, as well as pinpointing the optimum temperature for your home. Best Combi Boiler for larger homes

Best Shower for Combi Boiler

best combi boiler for showerThe high pressure hot water supply you enjoy with a combi boiler makes it ideal for those who love long, hot showers. You don’t need to worry about the hot water running out, as the combi boiler heats it on demand. This is unlike a system boiler, where you are limited by the amount of water remaining in the hot water cylinder.

A combi boiler is compatible with both mains pressure balanced showers and thermostatically controlled showers. However, if you replace a system boiler with a combi boiler, you should consult a specialist to see if the current shower is suitable for use with the new boiler, as the model could be one specially designed to be used in low pressure settings. It is best to avoid showers with inbuilt pumps when you have a combi boiler, as it can lead to excessive and potentially dangerous pressure.

In general, electric showers or mixer showers provide the best shower for a combi boiler, and it is worth checking your hot water flow so you can accurately assess the most suitable size of shower head. The bigger the head, the higher the flow needed to provide a decent shower experience. You can find out more about hot water flow in the best combi boiler reviews.
