Heaters from ring

[Eddiesparks]

Okay, so I am doing a Rewire at the moment and have put in 32 amp ring final circuits on the upstairs and downstairs. Kitchen will be on its own ring. Top floor feeds about five double sockets bottom floor feeds four double sockets. So not a great amount of sockets. There has been talk of getting an electric radiator in the upstairs bedroom, an electric towel rail in bathroom and one heater in the downstairs front room - it's quite a small maisonette.. Would it be a heinous crime to Spur these off their respective rings. I am guessing they would be about 2 kW as they are quite efficient. Basically my first fix is done and the decision about the heaters has been made afterwards. So this would be far and away the easiest solution. What do you all think to this? In my opinion it is no different, and in fact probably a better solution, than her plugging in a couple of 3 kW oil filled radiators into the existing sockets!

An educated guess will give them a idea.

by ONLY i suppose you would offer no advice then to the customer?

By only I mean I would only inform them of the running costs if I know the running costs.

I don't give out advice to customers based on guesses.

 

[wozz]

let them find out approach.

Well i would and have done and many people are surprised at the cost of heating properties with electric at peak cost.

 

[davesparks]

How do you go about working out the running costs then?

I assume you factor in the insulation of the rooms to be heated, number of external walls, any other heat sources, energy tariff they are on, efficiency of the heaters, size of the rooms?

 

[ferg]

Not to mention the average householders complete inability to use storage heaters properly.

Economy 7 and 10 also have much higher peak costs, so for a small property it may not be worth it depending on how much they use the heaters and usage during peak times.

ROINTE radiators are very good and on a plug too too !! Or you can fcu them.

Someone has been influenced by all the company snake oil hype!! lol!!

These things as i remember, are bloody expensive radiators (around 600 quid for a 2KW radiator) and are actually no better than any other manufactures products.

Heard all this old hype before, like any electrical radiator/heater, you basically get 1KW of heat output, for every KW of input. Anyone telling you any different, is is giving you a load of snake oil....

Get with the times Eng.
I've got a vphase unit at home and a 1kW kettle, I'm saving a fortune on tea brewing.

Haha..... If you say so... lol!!

Given that it's late and E54 is involved I am perhaps unwisely going to put my money where my mouth is.

The sales patter for modern electric heaters and boilers seems to be based around the near 100% efficiency figure in the advertising.

My argument is and always has been that the inefficiencies in electric heating are before it gets to the point of utilisation.
And those inefficiencies are still paid for by the end user.

Storage heaters are generally inefficiently used by the homeowner and consequently they rely on the very expensive convector part of the heater at peak rates.

All other usage is charged at a much higher rate as only the storage heaters get the benefit of the off peak rate, 2 meters, 1 through teleswitch, everything else through the other meter.

I live in a remote area so mains gas isn't an option it's either oil, LPG or electric heating.

When asked by customers what I use I have to tell them My heating and hot water is from a log burner with the option of using the Immersion for the hot water.

I can see that some electric radiators have the advantage of dispersing their heat over a longer period of time depending on what is between the element and the air but I fail to see how this can make them more efficient.

All I can see is the homeowner turning them up full til the place warms up and then opening a window when it's too hot.

I have quite literally lost count of the number of times I've been called out because of storage heaters not working.

Mostly it's the shutters fully open all the time and the windows open in the morning. Surprise surprise it's freezing at night.

Ferg, what i was trying to get over, is that this company Ronite, claims their heaters achieve 60% or whatever more efficiency over conventional heaters, which is just pure snake oil drivel!! They produce no more heat than any other electric heater for a given KW running cost. You will have just as good results from any electric heater. Oh and sometimes radiant heat is better than convection, especially for heating a small areas faster..

well heat loss will be fairly standard for that room no matter what heater you use, OP said no other heat sources, energy tariff easy usually a bill around, efficiency of the heaters? we are talking about electric heaters here dam near 100%, size of room is a constant aswel.

As simple as something like 3x3kw on for say 5-8 hours a day depending on what the customer does with their lives and how drafty it is, and you have a rough idea of running costs. Water wouldnt be hard to do either. No need to overcomplicate things or try to be too accurate this is a back of smoke packet thing to give a cvustomer who may never have directly heated a property before some idea of how expensive it can be in running costs compared to other forms.

Done it many times with electric underfloor heating when customers are still deciding, they would like for like compare the installation cost of a wet system and electric and go for electric as its cheaper. Without any consideration for running costs.

as for ROINTE only had a couple of brushes with them found their marketing drivel funny and over complicated, if a customer cant use a storage heater they have no hop with them heaters! Expensive from the start, and use expensive electricity. I did look at their unvented tanks and thought they were ok but never got the chance to use one.

its a forum its what we are here to do

My argument is and always has been that the inefficiencies in electric heating are before it gets to the point of utilisation.
And those inefficiencies are still paid for by the end user. erm so where are these in efficiencies going and what form of energy are they? heat?

Storage heaters are generally inefficiently used by the homeowner and consequently they rely on the very expensive convector part of the heater at peak rates. Nearly all storage heaters around here are as old as time and have no convector.

All other usage is charged at a much higher rate as only the storage heaters get the benefit of the off peak rate, 2 meters, 1 through teleswitch, everything else through the other meter. really depends on your tariff, when i looked at changing my tariff two rate peak wasnt much different to my average cost.

I live in a remote area so mains gas isn't an option it's either oil, LPG or electric heating. Bulk storage is rare around here Ive always assumed due to the cost.

When asked by customers what I use I have to tell them My heating and hot water is from a log burner with the option of using the Immersion for the hot water. Sounds ok if you have the time and routine some love them used the H2 system a couple of times.

I can see that some electric radiators have the advantage of dispersing their heat over a longer period of time depending on what is between the element and the air but I fail to see how this can make them more efficient. dont follow

All I can see is the homeowner turning them up full til the place warms up and then opening a window when it's too hot. Eduction is the answer then not rip the system out and put a more complex one in.

I have quite literally lost count of the number of times I've been called out because of storage heaters not working. Ive done a fair few but usually after years of service with no maintenance not many things we fit last as long as the old ones.

Mostly it's the shutters fully open all the time and the windows open in the morning. Surprise surprise it's freezing at night.Education?

Im not a hater just i havnt got on with them and their marketing is just baffling people, didnt they get done by the ASA for their marketing figures?

[Knobhead]

It’s a small maisonette not a sauna!

I don’t recall the OP asking about electricity charges and tariffs.

Or type of heaters.

they are about the same price as a storage heater believe you me they are good an efficient , they heat up a room very quickly and keep it there i have installed them in a bunk house replacing storage heaters , it virtually halved the running costs and with a built in frost stat stops the place from freezing to

 

[SPARTYKUS]

Best way to save on heating is to seal all drafts and line every room with half a metre of celotex. Probably wouldn't need a heater then, just a match

If the Ronite heaters can heat up a room very quickly and halves the running cost of storage heaters, then so can any other similar rated/spec'd wall mounted convection heater, that cost a fraction of these over priced units. As i understand it, the company has had more than a few run-in's/dealings with the Standards people about the unsubstantiated inflated claims being made for these heaters.

But if you're happy paying out that sort of money for a wall mounted convector heater, happy days to you!! lol!!
