A regular boiler is perfect if

  • You already have an existing regular/conventional boiler – old radiators are sometimes unable to cope with higher water pressure delivered by system or combi boilers
  • You have low water pressure in your area – as the water tank is in the loft, flow rate is controlled by gravity instead of relying on water pressure from your mains 
  • You have a large home where multiple taps and showers are on at the same time

How do regular boilers work?

To maintain the water level needed for your heating, a conventional boiler is linked to a separate cold water storage tank usually found in the loft. When you need hot water, a heat exchanger heats the water from the tank. Heated water is then pumped to a hot water cylinder where it’s stored ready for you to use. 

Why choose a regular boiler?

A comfortable and warm home

Unlike a combi boiler, you’ll be able to switch on multiple taps and appliances at the same time with minimal effect on your water pressure. 

Extra protection for your boiler

Our Worcester Bosch heat-only boilers are protected with up to a 10 year manufacturer’s guarantee.

Boiler types explained – how is a conventional boiler different from others?

There are three types of boiler – regular, system and combi:  

  • Regular boilers – these heat-only boilers are linked to a cold water tank kept in the loft. Water is heated by a heat exchanger and then stored in a hot water cylinder ready to be used.
  • System boilers – have a built-in heat exchanger in the boiler, so water is heated up and stored hot water in a cylinder. A water storage tank in the loft is not needed.
  • Combi boilers – not linked to a hot water cylinder or tank in the loft, water is taken directly from the mains and heated by the boiler on demand i.e. when you  switch your tap on.

Combi boiler or conventional boiler?

Should you replace your conventional boiler with a combi boiler? We recommend sticking to a heat-only boiler if:

  • You have a big and busy home where you need a supply of hot water to multiple outlets at the same time. Unlike a combi boiler, if multiple taps are running there will be minimal effect on water pressure
  • Water pressure in your area is low 
  • If you already have a conventional boiler and have older radiators

We recommend changing to a combi boiler if: 

  • You don’t need more than two taps or showers running at the same time
  • You want to save space and use your loft – combi boilers do not need a cold water storage tank or hot water cylinder
