Boiler Installation & Replacement in Edinburgh
A New Boiler Designed Around Your Home
Replacing a boiler isn’t simply a matter of fitting another appliance with the same output. The right boiler depends on the size and heat loss of your home, the existing heating system, your hot-water requirements, the number of bathrooms and how you actually use the property.
Thermatek Heating provides professional gas boiler installation and replacement throughout Edinburgh and the Lothians. We install modern condensing boilers from manufacturers including Worcester Bosch, Vaillant and Baxi, together with suitable heating controls and system protection.
Before recommending a boiler, we assess your existing system and discuss what you want from the replacement. That might mean a straightforward boiler change, converting an older system to a combi boiler, retaining a hot-water cylinder, upgrading controls or considering whether another heating technology would suit the property better.
Our aim is to specify a system that provides reliable heating and hot water without unnecessarily oversizing the boiler.
