The choice of boiler manufacturer is very important, at SOS Plumbing and Heating we recommend only the highest quality products.

Typically we would recommend the Worcester Bosch Greenstar, the Vokera compact He, or a boiler from the Viessmann Range. However if you have a specific boiler in mind we are able to install any boiler of your choice.

The reason we have chosen to fit the Viessmann, Worcester Bosch and Vokera boilers is that they are of the highest quality and through many years of experience we have found that these boilers have a long life span with the fewest breakdowns. Additionally, these boiler ranges offer a generous manufacturer’s guarantee.
