Heating room option?

Shefwedfan

Ok, nearly finished renovations. I completely stripped one side of house due to combination of dry/wet rot. Was a disaster.

Anyway now looking at section of house which was not renovated. I have kitchen, utility room and they are pretty cold. The kitchen is 4.7m x 8.4m and the utility is 3.2m x 2.9m. Quite a bit of floor space.

There is a single radiator about a metre long with double leaf to heat the rooms. The utility is closed off by double doors.

The kitchen it self has a large stove which also heats the house. Issue is standard evening after work when I come in last thing I want to take into is putting on stove. The radiator doesn't have the power to heat the room.

I have insulated the wall(pumped cavity) and attic but still not a warm room.

There isn't really wall space to put additional radiator. The stove itself is standalone on a plinth and there is large fireplace which is built in red brick. Looks like previous owner plan was to put stove in there but because they went with boiler stove they connected on other side of door. So at the moment there is nothing in fireplace/it has flue etc so could be used

No idea what else I could use in room to heat it, any idea's?

Handiest thing is to put in the biggest radiator you can find I imagine. Could you put an additional 2-meter tall radiator? A 2m tall x 48cm radiator could put out an awful lot of heat and could go in the space behind a door. A smaller tall radiator in the utility room would heat it up quick enough too. Of course you need to have adequate capacity in your boiler.

Radiator is currently 90cm x 50c,.

Going up is option but need to move phone etc as above it

Any high output radiators that could potentially fit into that space?

We changed from old rad to this and find it much warmer. It does take longer to heat up, but stays warm longer. http://www.theradiatorshop.ie/designer-radiators-ireland/427-zehnder-volcanic-black-free-standing-radiator-.html

My friend has them installed, raves about them as they hold the heat

I don't think output would be high enough. I done a quick calculator and I think I need over 7,000 BTU

I was looking at the following: http://www.theradiatorshop.ie/steel-panel-radiators/564-korado-radik-klasik-steel-panel-double-radiator.html#/78-power_options-central_heating_wet_system/1106-matching_pipe_cover_kit_-pipe_cover_kit_chrome_19_99/66-finish-white/1055-add_matching_valves-none/1225-size-600mmh_x_900mmw_5156btu_1511watt

I wonder what standard radiator would output?

The boiler is Grant and big enough for the job

You could use this. https://www.rvr.ie/products/elegance-2-0-350?variant=25299309255

I have one of these in the hall. It puts out a fair bit of heat. (You really need to look at manufacturer figures and work out the output and compare different models). It's pretty easy to move stuff like phones - it's not as if you need to redecorate behind the radiator. You don't really want to put stuff like that above a big radiator anyway. Clear ventilation around the radiator is obviously very important too, to get the most output.

A radiator that holds the heat is not any more efficient than a radiator that loses its heat right away!

You can look up the outputs of radiators on manufacturers/distributors' sites. Be sure to compare for the same delta (little triangle) T temperature.

There are high efficiency rads available ...
My dad has one with a built in fan, the inside looks like a car radiator...
It's about 3 or 4 feet long by 2 feet high and heats a huge room ...

Yep, according to the spec, these animals put out an awful lot of heat when connected to a high temperature system (like a typical oil fired central heating system).

People often get confused between high efficiency and high output. If you were to put a fan on any standard radiator (and assuming it had an adequate supply of hot water) you would get higher output from it.


The word "efficient) is often used in a manner that can give rise to confusion and lead people to believe they are getting cheaper heat.

A good example is the regular radiators without fins and the radiators with fins. The one with the fins give out more heat because the fins give it a higher surface (heat transfer) area. But this isn't free extra heat. For radiators of the same dimensions, the one with the fins will cost more to run, because they give out extra heat.

What I am looking for is high output. I am working on rest of house in regards to efficiency. At the moment as kitchen is main room it is issue that it is one of coldest.

I have looked at that Smartrad but I cannot see where it mentions output? on the technical spec it has 3 fan at 65 degree and has 4959, so I guess that is 4959 BTU?

Yes that's btu. Just check what the DeltaT is for that output.

No idea what DeltaT is. I done google and seems to be equation to work out output. Do I not just take the numbers from the guides?

Is there a way to check what type/model radiator is installed in the house? would they have something wrote on them?

Without going into detail, it refers to the output of the radiator at different throughput temperatures. You will see on some radiator sites that (for the same size radiator) they quote different outputs at different delta t's.

eg Old heating systems ran at a higher temperature than modern condensing systems. So to get the same btu output from a rad size that was used on an old system, you would need a larger one on the newer lower temperature system.

To check an existing rad, just measure it and compare it to the same type one on a radiator site. It should give the output for a given Delta T. Your plumber/service guy should be able to advise you of the delta t your existing system is running at. Simply put, it will be a combination of boiler temperature, flow rate and required room temperature.

Thanks for the help. Plumber is here this coming week and really what I was looking to do was swap out the current radiator and try and put a higher output one in its place.

Anything would be better so my thought was to find out what the current output from that radiator is and then see what I can buy in market that could potentially replace it with better output.

I know it might not 100% work like that but it will be short terms as the current oil/stove heating system is up for discussion once I finish off other renovations
