Good morning, wondered if anyone can advise please on a resolution?
My set up at home is that I have a 4-bed detached with 21 radiators (includes 4 towel rails), a 6m x 4m orangery/conservatory that was built last year with under-floor heating, and a Megaflo for storing hot water. The UFH...

Hi folks.
Sorry this is a long one. I'll try and keep it organised.
Son has just moved into a purpose built (2013 ish) 4th floor apartment as a tenant. No gas in the building. Triple glazing.
1. The letting agent led him to believe that the electricity supply was on an Eco 7 meter. He didn't...
Good day all,
I would like to get some advise and perhaps the solution to the issues with my UFH system.
We did install UFH in an entire house and got rid of all radiators.
The system is 14 port manifold (only 12 are in use) feeding 7 zones.
Total room area is 97 m2, with the biggest zone...
I wonder if anyone can help me. My house has under floor heating but after having a new boiler fitted it doesn't seem to working as it should do. I wanted to get the system balanced but some of the flow meters are stuck and not all of the actuator/flow valves seem to be moving as they should. I...
I have a UFH manifold from Wundatrade with a Grundfos pump. The pump feed has a mixing valve which has a hot inlet from the thermal store, and a cold inlet from the return manifold. In-between the mixing valve cold inlet and the return manifold, is a tee which returns the cold water to the...
My daughter has just had a new boiler, her system is radiators to upper floors and underfloor to all of ground floor. Despite the valve serving the underfloor being turned up to a high temperature and the pipe leading to the pump being very hot the flow and return pipes on the manifold are only...
Hi folks, hoping someone can help with a problem that's been perplexing me since just before Christmas..... I have a wet underfloor heating system installed in 2003 and manufactured by Underfloor Direct in NI - Now out of business. It's one of their triple tube systems and hasn't given me much...

So I posted a while back regarding my 300ltr unvented cylinder not seeming to keep any volume of water hot for very long.
Could it be the system boiler is not powerful enough? I have approx 220m2 of underfloor heating and the hot water cylinder’s . Does anyone know if Worcester Bosch Greenstar...
Hi
We have an UFH system part of the house (large kitchen / dinnner and utility room) and then Rad system for rest of house (10 rads).
We have noticed in this recent cold weather when both UFH and Rad are on (ie thermostatic driven) the UFH is robbing all the hot water and not getting round...

Hi everyone, we have a 1920s house with solid brick walls. The small front carpeted lounge (1.9 combined tog of underlay/carpet) with its own UFH circuit is struggling to get to 20 degrees. The UFH pipes run under about 5m of LVT to get to the front lounge.
My question is, can I boost the...
Hi all,
I've previously been helped on here by kind people so I'm tackling my next challenge. We have a GSHP (installed by previous owners) that supplies a buffer tank. That all runs OK.
The heating pump and manifold actuators are 'controlled' by three OJ Electronics WLM3s (one master and two...

Hi guys,
I have a set up with rads upstairs and UFH downstairs. I have installed the manifold for the UFH along with 2x Honeywell 2port values, one near the manifold and the other on the radiator side. I will be using Nest 3rd gen thermostats to control both the upstairs radiators and...

Hi folks, I’m in need of some sound advice.
We have recently had a ground floor extension and have had underfloor heating (company: JK UFH) installed throughout most of the downstairs. We have a few rads still left downstairs and the entire upstairs is still heated through rads.
We have a...
Hi, I’m hoping someone can help – I need a bit of advice / help as I'm not sure if the recent cold spell is too much for the UFH in the main living space (it's a barn conversion so 25ft high vaulted area) and I've checked all I can think of. It's 15 degrees despite all looking to be OK to me...
Hi
I have a 4 zone / 7 loop UFH system.
2 zones (4 loops) always get hot when the system is on when the zone thermostats and actuators are off.
The video posted shows when I turn on another zones the flow meters drop. (Kitchen prep and kitchen TV are the issue, two at either end of the...
Hello all. First time posting so apologies if this is answered elsewhere.
I am close to completing a purchase of my first flat, an ex-council place from the 1960s built in the usual concrete slab and brick.
At present there is some ghastly pipe work for the radiators sprawling round every...
Hi,
Having wet underfloor heating put in and been doing some reading, think pipe spacing is going to be 200 but read somewhere 100 from walls & sliding doors/bi-folds - is that correct ?
What distance would people recommend from kitchen units ? I have a run against one wall and then a 1200...
Is it ok to have more than one bypass valve on a system? Planning an UFH system (heat source supplied by air-water heat pump) with 2 manifolds, each with 6 circuits. Each manifold has its own motorized isolation valve connected to a room thermostat controller. Obviously the system needs a bypass...
Hi. I need to get a replacement flow meter as one has split and is leaking. I can’t seem to find the specific one and can’t see a maker on it. Does anyone know where to get one, what it is or any alternatives? Thanks.
