We installed this Vaillant Eco Tec 831 into a new extension in Hest Bank near Morecambe. We added radiators in the house, fully plumbed the extension and power flushed the existing heating system ensuring maximum boiler life. We also added a wireless programmable room stat, allowing the customer to control their heating from anywhere in the house. 
We also added thermostatic radiator valves to ensure the installation met all the energy efficiency regulations.
The valiant eco tec 831 is generally our boiler of choice in most semi detached properties. The hot water flow rate is good and the build quality is excellent.
We find that by using good quality materials our systems run hassle free, leaving us with many happy customers and a good reputation.
