Frequently asked questions

The surface of the radiators should be cleaned using warm water and a small amount of washing up liquid. Abrasive, solvents and spray cleaners – such as those intended for cleaning tiles and counter tops – should never be used as they can have a damaging effect on the finish of radiators. Clean especially at the start of winter, to avoid burning any dust accumulated during the summer.

The flex/power lead is on the right-hand side for the Haverland RCA, RCB, RCTT, RCTTi & RCE ranges of electric wall mounted radiators and conservatory radiators.

Quite simply - oil filled, gel filled and dry electric radiators are all electrically efficient, but may be more appropriate for your installation depending on your specific requirements and the size of the room that needs heating.

Dry heaters are designed to heat up both quickly and efficiently whilst you are in the room, ensuring that no heat energy is wasted when you do not require it. An Oil or Gel filled heater on the other hand will take longer to heat up and release heat into a room, but will heat your room for longer even after being turned off as that retained heat is dispersed slower.

Oil filled radiators are also deemed to be safer than a dry electric radiator as air flow to dry radiators can be affected by dust - therefore they can overheat and can be hot to the touch for children and pets in comparison to an oil filled radiator. There are specific low surface temperature electric radiators available for dry technology, although these are not widely available – they are a fantastic option for those who prefer the dry technology electric radiator.

Gel filled radiator is very similar to the oil filled radiator, but uses a thermodynamic gel compound as an alternative to oil for heat diffusion around the internals of the radiators metal construction.

Please see our Which Electric Radiator should I choose? Gel filled? Oil filled? or Dry? article for further information.

Haverland RC10TTS Inerzia - Electric Radiator, 1500W

The heaters look good and were installed easily.The information supplied by Haverland less so. for the heaters we selected these as not requiring a smartphone to programme we do not have a smartphone. Fortunately the electrician did and we could use the or code on the leaflet. Now I have to get a download for the future when this should have been sent with the heaters.

Now the towel rail, no information on installation and programming and the display is not intuitive we cannot even ask it to turn on manually. I now have to get a download for Tod7. So a rating of zero for information

Tracy was very helpful when we had to wait for a split delivery as you were waiting on Haverland. The final two arrived just in time for our installation date

Excellent, I would like an option that the delivery person would carry the radiators up stairs as I live in a flat. I was aware that the delivery would only be to the ground floor on this occasion. The delivery was very good, I selected before 10am next day and the radiators arrived next day at 9 am. The radiators are very good, well packed and a competitive price. I rang with an enquiry before placing my order and the representative I spoke to was helpful and polite. I would use again.

Thank you for the really great review.

We would really love to offer the service that you require, however the carrier services themselves do not offer it due to insurance, so at present we are unable to do so.
We will continue to pursue this as an option if any of our various carriers offer it in the future.

The heater is fantastic compared the the old storage heater, it gets the room to correct temp with in 15 minutes and keeps it at the desired setting

The online order was easy , I was told the heater would be delivered on the Monday but never arrived so on the Wednesday I phoned the heater shop and was told the heater was out of stock but should be that day and as soon as it arrived they would dispatch it , it arrived on the Friday .

Thank you for taking the time to review us.
Due to the item being out of stock we did call you and email you to offer an alternative and explain the options of either waiting or receive a replacement with next day delivery, but we were unable to get a reply, so assumed that you were happy to wait for the original order.
I am very sorry for any confusion that this may have caused.
