Can I get this system working? Follow me along as we look into this problem heating system that 3 plumbers couldn’t get going.

My rads are absolutely not balanced. However, as I only have 4 rads total all of which get proper hot, and the downstairs is on wet UFH, is there actually any point balancing?
Great video, and funny presentation, really enjoyed watching.
Is it worth keeping the rad next to the back door on fully as most of the heat will go out the door when the door opens?
Do you every wear flip flops when working in a customers house when you have to take your boots off?
⭐️⭐️⭐️👍👍👍👏👏👏👏🍺🍺🍺 nice one🥵🥵
Excellent work and great knowledge
your videos are amazing! You mentioned that you were in Costco in Stevenage. Are you anywhere around this area in Hertfordshire?
Great video mate. Thanks for sharing.
You've mentioned self balancing valves were not set correctly but you didn't show this in the video. Perhaps you could share when you get a mo? Thanks mate 👍🏻
Not a plumber myself, but having looked deeply into mixed UFH/radiator systems it is highly possible that UFH is stealing flow from radiators. If I recall UFH is something like 3-4x the flow rate of rads. If both on at the same time, rads suffer. More to it to that obviously – Andrew Millward on YT a good resource
If the trv in the room with the wall stat is on 6 then surely the room stat will be shutting off prematurely and the other rooms won’t be getting enough heat. I would have thought it better to put the trv in the room with the wall stat at 3 or below to prevent it getting up to temp before the other rooms had warmed up.
Brilliantly explained , Many thanks .
Condensing boilers do not require a trickle through the bypass. This causes lower efficiency by raising the return temperature. The instructions say how to set this up correctly.
With no hydraulic separation the underfloor heating may draw more than its share of water from the heating system in competition with the radiators. The type of manifold fitted at this property is for high temperatures and the boiler temperature needs to be set high
Well done for us people who get lost with rads hope mine get better after watching this
The room stat on the landing picks up heat from the ground floor. This should be in the master bedroom
auto bypass valve
At 18:40…SO TRUE! It is so unprofessional to slag off a previous operatives work; in any trade. I have left a customer's house before now at 10 at night and told them "brain is fried – I'll be back in the morning". The only time I'll comment on previous work is when it is actually dangerous (I'm a sparks, I follow James's channel out of interest) Even then, a quiet explanation is all that is normally needed; not a hissy fit – that just disturbs the client to no win for anyone.
When that gas boiler is knackered in a few years I’d suggest a air source heat pump with minimum zoning, no buffer and get some solar on them overly large roofs. 7kW Vaillant should heat that home and hot water no problem. Just make sure you use a Heat Geek approved installer. I love my system and my house is lovely and warm all year round and costs less to run than my combi gas boiler did. This was only 10 years old and it was also a condensing boiler. Cost was over £1000 per year to heat my hot water and my home (large 4 bed 1950’s semi) back when gas was dirt cheap at 2.3p per kWh. It’s way more than that now for gas. I pay 7p per kWh for my electricity and I store that cheap night time energy rate in a large home battery so I’m never pulling any expensive day rate of grid energy. To heat my hot water and home now costs me less than £500 per year.
Hi James. Something that would be helpful as well is a somewhat in-depth explanation of how to correctly set an auto bypass. The instructions in the box goes over my head. Im sure not many people understand it. Or i might be the only one too dumb to understand them.
Wouldn’t this guy be better off with weather comp and fully open all the TRV’s. Lower his flow temp as low as possible so his home is comfortable say 45-50 degrees heating flow temp?
So I knocked down all the lock shields to a quarter turn, all still very toasty – whistling like mad though – next video on solving whistle/rushing?
Currently in the middle of renovation, the system is down about 4 rads – is the flow pump running too fast? No air in the system
I’m surprised the original installer didn’t fit a LLH in there as those rad circuits will be fighting the UFH circuit….
Very nice house though 👍
Thanks Adam,great video & nice legs!We use the Drayton Wiser TRV system in our house.No longer reliant on thermostats in weird places! Effectively each room with there trv has its own thermostat! & can be programmed independently.
(No I don’t work for them!)
