System Boiler Installation in Whelley
System Boiler Installation in Whelley
Where a Whelley home has ageing cold and hot tanks in the loft, moving to a fully sealed system boiler + unvented cylinder cleans the loft up and improves shower pressure noticeably. Larger Whelley homes — particularly across Victorian terraces sloping up from the town and 1950s semis higher up the hill — often outrun a combi at peak demand, which is where a system boiler and unvented cylinder comes in.

Whelley FAQs — system boiler installation
Warranty length?+
Up to 10 years on Vaillant ecoTEC Plus and Worcester CDi Compact system ranges when registered on install day.
What's the difference between a system and a combi?+
A system boiler heats the radiators directly and stores hot water in a separate unvented cylinder. A combi does both on demand with no cylinder.
What size cylinder do we need?+
150L covers most 3-bed / 1-bathroom homes; 210L or 250L for 4+ beds and 2 bathrooms.
Do we need a G3 unvented ticket for the cylinder?+
Every engineer working on the unvented cylinder here holds a current G3 qualification — it's non-negotiable.
Is a system boiler more efficient than a combi?+
At full load, similar. On real household usage they're usually a couple of % less efficient than a combi but win on high hot-water demand.
