Which Boiler is Best?
When choosing a specific boiler or brand, it’s important that you make a decision based on reliability and reputation. A new boiler should last around 15 years, which means it should also help you through 15 different winters and needs to do the job well.
It’s always very tempting to go for the cheapest option. Whether this is a brand like Biasi, Ferroli or Alpha, it’s often an easy choice because of the appealing price tag for the installation. However, what often gets overlooked are the expenses towards frequent boiler repairs if the boiler itself isn’t a high enough quality.

Best combi boiler for 3 bedroom house – What is a Combi Boiler?
Before we explore the best combi boiler for 3 bedroom house, we need to clarify what we mean when we mention a ‘combi boiler’.
In the world of boilers, ‘combi’ is short for ‘combination’, and combines all the components for hot water from your taps and central heating in one, compact unit. This is different to other types such as the regular or ‘open vent’ boiler that typically require a cold water storage tank in the attic and a hot water cylinder. With combi boilers you can save a lot of space, as well as only heating up water when it’s required, saving you a lot of money in the long run.
Energy used to heat the water is kept to a minimum. Nothing is wasted trying to keep your water constantly heated.
Many combi boilers available today will be able to provide heating and hot water, but you’ll need to choose one with the appropriate output to cater for the number of bedrooms you have. Even then, as long as you get the right support from industry experts, you’ll be guided through anything that you’re unsure of to make sure you don’t miss out.
Unsure on how combi boilers work? Take a look at our detailed guide.
How does a combi boiler work?
Central Heating
If you look at the cross-section diagram below, you’ll notice that combi boilers house two separate heat exchangers inside the compact unit. For the primary heat exchanger, its focus is on heating water from the mains supply to go straight to your radiators. As your radiators are then heated up, the water is returned back to the boiler where it continues to operate. This is the ideal result we want when deciding on best combi boiler for 3 bedroom house.
Because this heated water has now passed your radiators, it’s prone to collecting the magnetic sludge, grime and dirt that can get deposited at the bottom*. With this in mind, you definitely don’t want to be drinking from the same source as your central heating…so how do we get clean, drinkable water from a combi boiler?
*You can avoid a build up of magnetite sludge and rust by having a magnetic filter installed at the same time as your boiler. Read our article on Are Magnetic Filters Worth it? for more information.
DHW (Domestic Hot Water)]
The sludge that ends up mixed with the magnetite sludge in your radiators means it’s complete unsafe to drink (as it would be anyway). However, this same water gets used again because the heat produced can still be recycled thanks to the boiler’s secondary plate heat exchanger. As well as this, the reason you’re able to switch between your central heating and hot water supply is the boiler’s diverter valve. It’s when this switch takes place that you may be able to hear a ‘clicking’ sound when you turn on your taps for hot water.
What is a Storage Combi Boiler?
Besides the traditional combi boiler that most people know in the UK, storage combi boilers offer a good alternative for anybody needing a little more to heat their homes. Storage combi boilers come with an integrated hot water cylinder inside the boiler itself. Because of this, they’re a great choice for homeowners with a higher demand for water, as well as anybody who wants to save on space. Remember: They don’t require a cold water storage tank, or a separate hot water cylinder elsewhere in the property.
With this in mind, an example like the Viessmann Vitodens 111-W can provide the hot water you need at a rate up to 18 litres/min. This is for properties with around 2 bathrooms, so they may very well be a good choice if space and water demand are an issue for you.
