Quick answers on boiler installs in Welwyn Village
Where do boiler leaks usually come from?▾
Most common: pressure relief valve discharging because system pressure is too high, a perished pump seal, or a failing heat exchanger on older units. We diagnose properly rather than guess.
Should I turn the boiler off?▾
If water is actively dripping and you can see it pooling, yes — switch the boiler off at the spur, and turn the system pressure down via the filling loop if you can. Then call us.
Do you take the old boiler away?▾
Yes — old boiler, packaging and any redundant parts are removed and disposed of properly at no extra cost.
Which boiler brand do you recommend?▾
Worcester Bosch and Vaillant for long warranties and parts availability; Ideal Logic Max for budget-conscious installs. We'll explain trade-offs honestly.
