Electric radiator vs oil filled radiator

Scatty

I have Rointe electric radiators. Still not worked out programming yet but getting help with that next week.

The landlord left an oil filled radiator for supplemental heat. I was wondering whether, until the REALLY cold weather sets in, I would be better buying another one and setting them both on timers (bedroom, lounge) but I'm not sure on running costs. I do know I'm going to be coughing up loads of dosh by next summer whatever I do :eek:

Thank you

Look at the oil filled radiators. They should have a rating in watts. If it's rated 1000w it will use 1kw/h for the time it's switched on. The good thing about oil filled radiators is they still give off for a while once you turn them off. They came in handy when I lived in a static caravan.

You can buy supplementary heating and have it in your home and working in an hour any day of the week,. We have no idea how many Rionte panels you have, tariff, etc so no one including you or your landlord has any idea at all. Why don't you wait and see, prep such as it is would be onsies and duvets.

Assuming you want the same amount of heat in your bedroom & lounge the running costs would be exactly the same. No electric heater is any more efficent than any other.

What anyone would want to pay £550 for a 700W Rointe electric radiator or £875 for a 1600W Rointe electric radiator either of which would struggle to heat a normal EPC living area in the winter defeats me. They would need to be run permanently 24/7 on core day-rate electricity costs - that's similar to the price of a fully functional NSH which can be run 7/24 on cheap night-rate electricity costs.

You could buy 29 individual Prem-I-Air 2KW convector heaters for £30 quid each with free delivery from Amazon and bracket them on the wall with the supplied brackets for the same price as one Rionte and get 25% more on-demand-heat. Alternatively but the one £875 for a 1600W Rointe, and use the £845 quid you save to pay your annual electricity bill ..... MSE .. .. .. madness !

Snake oil, Marmite or liquid gold filled, the time it takes to cool down is directly related to the time it takes to warm up.

If to raise a room temperature from 9.2ºC to 21ºC on an 1.5kW Aluminium/steel fluid-filled radiator it takes 1hr 34mins [and it does] it takes a similar amount of hours and minutes to loose it - meanwhile that 1hr 34mins you remain cold, you win nothing ! Ditto a 1.5kW Steel panel convector will take I]reduced by only10 minutes[/I 1hr 24mins to to raise a room temperature from 9.2ºC to 21ºC [and it does], but you lose at the same rate, you win nothing !

My tip is don't wait until next summer, request a payment card and make a weekly payment at the post office, paypoint or even online. And phone up with meter readings after a week and then you can get idea how much it is costing you per week.

But that time is equal to the extra time they take to heat up.

The only real advantage to oil filled (IMHO) is that there is no exposed heating element which means that you don't get the smell of burning dust (or whatever else has fallen on the element), and they are a little safer.

From the point of view of conservation of energy, it's true that 1kWh of heat will consume 1kWh of electricity regardless of the heater type, but radiant heaters are more efficient.

This is because they heat you directly, whereas convectors heat you indirectly via the air, and because radiant temperature has more effect on your heat loss than air temperature does. This means radiant heaters can achieve the same subjective level of comfort with a lower air temperature, and lower fuel consumption.

(NB: The term radiator is a misnoma, 'radiators' heat by convection, a radiant heater is one with an element that glows red.)

While I understand what you are trying to say, I think it is just confusing for your average person. You could say that the heat transfer process is more efficient, but the heater is not.

The trouble with radiation only heating (such as infra red), is that the heat is more rapidly lost from your body due to the cold air around you. A mixture of convection and radiation gives the most comfort.

In my personal experience, I have never found radiation heating to offer much comfort. There seems to be always some part of you that is obscured from the radiation source, and that part often feels very cold.

They were supplied by the landlord, I haven't shelled out any money for them, I just have to learn to live with them. I wouldn't have chosen them - I would have installed central heating if I owned the house.
