Up Holland FAQs — system boiler installation
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.
Can we keep the existing cylinder?+
If it's a modern unvented and in good condition, yes. Old copper vented cylinders we normally replace during the upgrade.
Warranty length?+
Up to 10 years on Vaillant ecoTEC Plus and Worcester CDi Compact system ranges when registered on install day.
