At Northlake Plumbing we are now offering some very competitive prices on Vaillant boiler installs. Manufacturing since 1874 Vaillant the company have two ‘Best Buy' recommendations from Which magazine for their ecoTec range. Vaillant now come with a comprehensive 2 year guarantee and enjoy a reputation as Britain's most widely used boiler (it accounts for 70% of the boilers in UK homes) with a 24 hour service to back it up. Older type boilers tend to waste a lot of valuable energy, with many converting as little as 60% of your expensive gas into useful heat. By comparison a condensing boiler from Northlake can increase efficiency to produce a conversion rate of up to 98%.
