Hello,
I’ve moved into a property with a conventional 6-year-old Vaillant boiler with water tanks and a single pipe system. Initially the downstairs radiators wouldn’t heat up. After having new lock shields and TRVs fitted, system power flushed and new pump installed, all radiators heat up but downstairs not as hot as upstairs.
On Central Heating only function the temperature on the boiler rises very quickly and it switches out, as temperature drops it switches back in again. When hot water and heating are both on, this is less of an issue. Been advised it’s a circulation problem and boiler display indicates this.
Is it advisable to get the existing pipework replaced with combi boiler and two-pipe system? Dilemma is that I’m having flooring replaced so it’s an opportunity to get pipework upgraded while flooring is up. However existing system still does the job despite issues outlined. Would really appreciate some advice.
Cheers
