Common questions about boiler installs in Little Dunmow
Why pick Vaillant over Worcester?▾
Vaillant tends to edge ahead on hot-water performance and very-quiet operation. Worcester edges ahead on warranty length and parts availability outside London. We'll be honest about which fits your situation.
Do you stock Vaillant parts?▾
Common parts (PRVs, expansion vessels, F22 sensors) yes — on the van. Less common parts come next-day from Vaillant directly.
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.
