We had a quote from British gas for £4700 to convert our old tank, cylinder and back boiler system to a combi boiler system. Mike from SWR quoted us allot less, installing the same boiler as British gas. Very clean and tidy, professional lads with a lot of energy. Will recommend to any one.

Claire Fisher, Over Lane Bristol

Over the years we have had the pleasure of working in the homes and businesses of Bristolians from all walks of life.

A typical month would see us servicing a Vaillant ecoTec boiler in Henbury, 
running gas supplies to feed a brand new heating system installed and commissioned by us in Clifton Wood, 
installing LPG systems for Hopkins motor sports, 
visiting tenanted properties in Long Ashton to provide landlord safety checks, 
changing blown circuit boards in Hallen due to a power surge, 
or providing gas solutions for customers of Andy’s Gas Cribbs Causeway.

My boiler had broke down in Winter. I called a few guys for the quote. But this guy gave me a quote that I couldn’t refuse. He installed new boiler after 2 days and finished in a day. I am very satisfied customer. I don’t have to worry about my boiler now. If anything goes wrong, I can call this friendly guy anytime. I recommend this guy to everyone.

We are proud to be Vaillant accredited boiler installers

Vaillant is an exceptionally well engineered boiler with a great customer service standard and is a strong mover in the heating business. 

Most plumbing and heating companies and heating engineers will install or recommend these boilers over any other.

Boiler installation location

If it's a straight swap then it's simple…

In terms of new locations for boilers then the sky’s the limit really. 

They can go in the loft, kitchen, bedrooms, dining rooms, 

garages and even in bathrooms. 

Of course we are governed by regulations so will install accordingly.

Room sealed appliances such as combination boilers or conventional boilers are very accommodating when it comes to 

potential places to sight them.

The things we have to consider is how we get services such as gas, water and heating pipes to the boiler, and how to get products of 

combustion and condense away from the boiler. 

We also have to consider running an electrical supply to a 

fused spur to supply the boiler.

If you already have a combination boiler in place then we may only have to bring a 22 mm or 28 mm gas supply to the boiler 

(if the existing supply is too small) 

and a condense away 

(if your old boiler is a non condensing).

We can typically follow the same flue route and connect 

to the services, primaries and electric.

Running a shower from a combination boiler

Combination boilers sized correctly and operating from good mains pressure can provide fantastic power showers. 

Bear in mind that  a good shower is around 12 litres per minute. 

This means for households or businesses with a mixer shower fed directly off of the boiler a 24 kw unit will be undersized 

and will not be suitable for showers. 

Boiler installation Bristol – A 24kw unit such as the Vaillant Ecotec Pro 24 (ERP) or Worcester 24I junior will give between 8 litres – 9 litres per minute depending on incoming cold water temperature 

and incoming mains supply. 

This is no good for a decant shower, especially if someone draws off hot water at the same time (essentially the flow rate will half). 

Boiler power (in kilowatts) behind the hot water supply 

needs to be 28 kw absolute minimum. 

We would recommend a ecoTEC pro 28 (ERP) minimum, 

however a Vaillant Ecotec Plus (ERP) 832 or a Worcester 30 CDI 

in shower situations will be perfect. 

Both boilers delivery over 12 litres per minute – which is a good shower.
