Hydronic Plinth Heaters?

Hi folks,

Can anyone recommend a hydronic plinth heater? Inundated with options and they all look the same to me. I plan to swap a 90 degree for a T so I can run a flow and return to pretty much any unit.

The ones with the coffee maker on will contain food, so probably not ideal?

On the other side, where the rice maker is, I can fit it really easily as that is a 700mm cabinet. But then it'll be tucked in the corner and presumably central is best. Power is no problem to anywhere, really.

Hydronic (Central Heating) Archives

Hydronic central heating plinth heater connects and works with central heating system. Hydronic models not only save space they are also cheaper to run.

Thoughts? The room is 4m long by 3mish - but I'd also like to heat the utility (1.6x2m ish).

Not commenting on the topic, but that looks good already.
Glad you made the changes to units as discussed.

You should ask them to cut off the bottoms of the fillers either side of the sink unit IMO. Unless they are only just slotted in right now

Thank you. I wish I could ask "them", unfortunately it is all my own handy work :D

I've left the fillers long because I was undecided. I can unbolt/trim/make a decision when I fit my floor, but I am leaning to that same conclusion.

I had a similar choice for the filler panel by the ovens and decided to cut flush with the base, so makes sense to match up the Belfast I think!

Ah ok, I fitted mine as well and its all about time :)
Nothing too hard just take your time and get the fit right :)
 
Smiths was slightly out of budget so I've ordered an oversized Thermix KPH 2400 with WiFi/Thermostat:

Thermix KPH 2400 Classic Hydronic (2350 watts/ 8020 BTU)

Thermix KPH 2400 Classic Hydronic Plinth Heater is a high output fan convector for larger kitchens and areas needing an energy efficient heater

This should push enough heat on "low" setting to heat the kitchen and the utility (theoretically...).

I've had a Smiths SS7 in both kitchens I've had, never had an issue with them. https://smithsep.co.uk/wp-content/uploads/2022/08/SMTH_Datasheet_SPACE_SAVER_HYDRONIC_16.pdf

They do the SS9 which is for larger areas, so should be an option to suit.

Did you find it warmed the cabinet above massively? The best location is where all the food is kept, or under the fridge...
 
Nope, barely put any heat into the cabinet. If you mount the heater in the middle of the plinth, it has at least a couple of inches above it, so doesnt touch the carcass of the units at all, and as the heat is blown out the front the casing stays pretty cool.
 
Our plinth heater in our last house was both in a corner, and under a food cupboard. We didn't find that either of those caused an issue. I thought it worked brilliantly, and would unreservedly recommend them to people wanting to avoid a radiator in the kitchen. I was frankly amazed at how good they are. Within 1-2 minutes of switching on the heating, the fan would kick in and already be distributing warm air.

The only problem we ever had with it - and I think I've said this before on here - was the dog sitting in front of it looking guilty and stealing all the heat.
 
Jumping onto this as it's piqued my interest, what is the fan noise like?

I'm pretty picky about noise but then it is in a kitchen. So long as I can't hear it from the living room next door I'd probably be happy...
 
They aren’t quiet but not intrusively loud. The fan isn’t on all the time anyway.

How have you found the Thermix, are they any good and what's the noise level like?

Absolutely spot on - no issues and it heats the room no problem. I actually thought we had an issue the other week as the kitchen was cold; I had just knocked the fan switch off. Whacked it back on and toasty warm again.

Noise is...well, a fan - so you can hear it. It isn't silent. It is a reassuring "I am on noise" in my opinion.

I’d like to get one of these for my kitchen which is easily the coldest room in the house. The challenge is that with a heat pump the flow temps will never be high enough to trigger it. I’ve heard it’s not hard to adjust it or trigger it with a WiFi/zigbee relay but not sure I want to go there!

I'm almost certain Thermix is a bloke in his shed. Give them a call - the guy is a legend.

I wouldn't bet on that. As I posted above, I found the fan kicked in very quickly - when the pipes were still only lukewarm. It certainly didn't require the water to be piping hot.
