Energy efficient radiators

Nickindublin

I have a fan heater. If you set it to 20c it will not cut out until it hits 22c or more. So what Baines is saying makes a bit of sense. Also Wear what you are saying is true too. 1kw of heat is 1kw no matter what heater you use.

Nickindublin I'm sure you'll be happy with you're heaters...and still happy in a years time when you've lived with them.

Wearb, 1kW of electricity is equal to 1kW heat, it's a 100% efficient conversion, all heaters are 100% efficient in this aspect. The efficiency I was trying to describe is for the use of the heat produced.

I am sure you mean all ELECTRIC heaters are 100% efficient. If you want to talk about efficiency of "heat produced" you need to describe what you mean by that and not be changing the goalposts.

If I understand what you mean by efficiency of heat produced, then you are talking room insulation and not more efficient heaters.

I thought that it was clear that I was talking about the heat produced by the heater, it mustn't have come across.

I'm not talking about insulation directly. I'm talking about heat in the room. If you have a minimum temperture requirement for comfort of 20°C, then ideally your heater will have completely even distribution of 20°C throughout the room, maintaining it constantly, when required. This would be a 100% efficient use of heat.

Unfortunately there is no heater that can do this...but the closer a heater gets to this, the lower the heat requirements, the lower the running costs.

I didn't really want to get into a debate on this, I just wanted to give my opinion on the subject. Whether people agree or disagree, that's my opinion.

Fair enough. I just wanted to add another dimension also. I saw that the thread had nearly 2000 views and wanted to make sure that those interested knew that there was other views. Keep posting, that's how we all learn.

Ah yes... I see where your coming from. I suppose that is the whole idea of boards.ie!

I have just got 3 Technotherm radiators installed to replace storage heaters. Nice looking radiators. Turned them on for about 20mins to test them. Give off a good heat and they stayed warm for a good 20 mins after turning them off. Wont know what the running costs will be until the winter comes. Will report back then.

Hi. How have your radiators worked since you installed them last year? Thinking or installing them in my duplex apartment.

Also interested in Nickindublin's experiences with the Technotherm / Lucht LHZ heaters. Like paudiel, I'm thinking of replacing three 13-yo storage heaters in a duplex apartment.

Interested in improved controls so we're not heating the place while we're at work, holiday mode and frost protection modes.

Ability to control multiple heaters in one living space would be a huge bonus.

Any data on total heating cost per year compared with night storage heaters would be great!

I would like to know how the Technotherm performed as I am about to commit.

Sorry just seen this thread again now. I find them great. They take a little while to heat up but then they stay warm for about 30mins after they turn off. There is a good time which let's you control them by the hour. You can set holiday periods etc.

We have a 2 bed apartment and have the radiator set to 21.5c in the living room. It's on for 2 hours in the morning and 5 in the evening Monday and Thursday. Tuesday it's on 2 hours in Morning and 8 in the evening. It's on for 17hours Wednesday, Friday and Saturday and 14 hours Sunday. The bedroom is set for 20c and is on 12hours everyday. We are on nighsaver and our bills average at 100 a month all year round. I don't think you will save a lot of money but you will be warmer😉 IMO BTW our apt BER C3

Has there been any research into the comparative efficiency and cost benefits of the different brands of new era electric radiators: Technotherm, Lucht, Jouletherm, etc. Am considering going "electric" for a small house renovation, but am confused by all the brands out their and the claims (I think Jouletherm claims 10-15 minutes of heating gives out 1 hour of output from a radiator, for example)

Also, any opinions on the use of Positive Input Ventilation (with integrated heater) in combination with these radiators - as I note the opinion that the even diffusion of heat throughout the room is a key element in reducing heating costs.
