Why Choose a Vaillant Advance Installer?
Not all heating engineers are equal. Vaillant Advance Installer status is awarded only to engineers who have completed specialist training directly with Vaillant — covering product knowledge, installation procedures, and customer care standards.
Choosing a Vaillant Advance Installer means:
- Enhanced warranty protection — Advance Installers can offer extended guarantees not available through standard engineers
- Expert product knowledge — every installation is carried out in line with Vaillant’s technical specifications
- Tailored advice — we recommend the right boiler for your property, budget and heating requirements
- Full compliance — all work meets Gas Safe and Building Regulations requirements
- Aftercare included — from annual boiler servicing to emergency repairs, we’re here when you need us
CGH Services has served homeowners across Bath for over 25 years. As a former British Gas engineer, our founder brings a level of experience and technical rigour that sets us apart from newer entrants to the market.
Vaillant Boilers We Install in Bath
We install the full range of Vaillant ecoTEC boilers — combination, system and open vent — across all property types in Bath, from Georgian townhouses and Victorian terraces to modern apartments and new builds.
Vaillant Combi Boilers
The most popular choice for Bath homes, a combi boiler heats water on demand directly from the mains — with no need for a separate hot water cylinder or cold-water tank. This makes them ideal for properties with limited space or a moderate hot water requirement.
Vaillant’s ecoTEC combi range is highly efficient, compact and straightforward to maintain. Our engineers will advise on the right output size for your property during a free home assessment.

Vaillant System Boilers
A system boiler works alongside a hot water cylinder, making it a good fit for larger Bath homes with higher hot water demand — multiple bathrooms, for example. Unlike traditional systems, Vaillant system boilers connect directly to the mains supply, so there’s no need for a cold-water tank in the loft.
Many system boilers also support an electric immersion heater within the cylinder, meaning hot water remains available even if the boiler needs attention.

Vaillant Open Vent Boilers
Open vent (or regular) boilers are the traditional choice and are commonly found in older Bath properties — particularly period homes with existing gravity-fed systems. They work with a separate hot water cylinder and a cold-water tank, typically located in the loft.
If your home already has this type of system, replacing like-for-like with a modern Vaillant open vent boiler is often the most straightforward and cost-effective option. Our engineers will assess your existing setup and advise on the best route forward.

Frequently Asked Questions
How long does a Vaillant boiler installation take?
Most standard Vaillant boiler replacements are completed within one day. More complex installations — for example, moving the boiler location or upgrading from an old back boiler — may take two days. We’ll give you a clear timeframe at the quotation stage.
What warranty comes with a Vaillant boiler installed by CGH Services?
As Vaillant Advance Installers, we are able to offer enhanced warranty packages beyond the standard cover available through non-approved engineers. Full details are provided at the quotation stage. You can also find information about Vaillant warranty terms on the Vaillant website.
Do I need a powerflush before a new Vaillant boiler is installed?
This depends on the condition of your existing system. If your current pipework contains sludge or debris, a powerflush before installation protects the new boiler and helps it perform efficiently from day one. Our engineers will assess this during the home visit.
Are your engineers Gas Safe registered?
Yes. All CGH Services engineers are fully qualified and Gas Safe registered. You can verify our registration on the Gas Safe Register website.

Yes — we provide emergency callouts across Bath. If your Vaillant boiler breaks down, call us on 07308 355077 and we’ll get to you as quickly as possible.
