What moves the price
- Type of tank — an unvented hot water cylinder needs safety valves and more skilled fitting than a vented tank.
- Installation complexity — getting a large tank into a loft or a tight hot press takes extra hands and time.
- Any necessary modifications to existing plumbing — pipework that does not suit the new tank's connections needs rerouting or replacing.
- Tank size — a larger cold water tank or hot water cylinder costs more to buy and is heavier to lift into place.
