Popular Boilers In East Dulwich, Southwark

Vaillant Boilers
Vaillant are one of the most popular boiler manufacturers in the UK. They were arguably the first company to make a “combi”also known as a “combination” boiler back in the early 1960’s. So they’re a well established company.
Worcester Bosch Boilers
Worcester Bosch are probably the best known boiler brand in the UK. Like Vaillant and Viessmann boilers, Worcester boilers have recieved lots of Which? Best Buy awards.


Viessmann Boilers
Viessmann are the greatest boiler make you’ve never heard of. We’re big fans of Viessmann here at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, but their prices are a little lower. This makes them fantastic value – and Which? agrees, giving Viessmann boilers several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi Boilers are another well established British heating make, founded in the industrial revolution by Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. These days, Baxi also makes boilers under the Main and Potterton brands. We recommend Baxi boilers as the least disruptive replacement for some conventional boilers – and their Main boiler brand for people who want to keep costs down.

FAQ​
Generally, if you‘ve one bathroom and also excellent water pressure at your kitchen tap or outdoors tap, a combination central heating boiler is generally the best choice for most people.
If you‘ve got over one bathroom, a conventional, also called a “heat only” central heating boiler (and even a system central heating boiler) with a hot water cylinder could be the most effective choice.
No. For existing homes, if you need to replace your central heating boiler from 2035 onwards, you will not be able to replace it with another gas central heating boiler. Going by current government plans, you would need to install a Hydrogen boiler or a heat pump. However, if your gas central heating boiler is operating in 2035, you will not be required to do anything until it needs to be changed, such as if it’s broken down and beyond repair.
It can differ hugely depending on what you require.
However as a rough guide, to take your old central heating boiler out and put a brand-new one in the same place ranges from about ₤1800 to ₤3000.
And strip out an old sort of gas boiler with a hot water storage tank {and} put in a combi central heating boiler costs between about ₤3000 to ₤5000.
If you require other work carried out at the same time, such as a power flush, a new gas pipe, or new radiators, this will certainly add to the estimated costs.
If you‘ve only got 1 bathroom and also excellent water pressure, yes.
If you‘ve got more than 1 bathroom or inadequate water pressure, then no{, you should look at a conventional boiler or a system boiler}.
