I want to remove a radiator but we need heat.

[ILiveInSalemsLot]

I have a big radiator across a wall behind the dining table in the kitchen.
It’s a bit squashed and I thought that removing the radiator would give us a lot of space. We need heat in the room so I thought of replacing it with a tall radiator using the same pipe connection. Although it’s an option, I don’t really like tall radiators.
Can anyone think of any other way I could heat that room?

Heaters that fit under the base cupboards at floor level in the plinth space, or underfloor heating if you're redoing the whole space. Or maybe you can find a smaller slimmer more efficient radiator instead of a tall one. It's what we had to do.

"big?"

What dimensions?

What size is the room it is heating?

If the rad is against the wall, how much room does it take up?

When the room is adequately heated in cold weather, how hot is the existing radiator? Does it have a TRV?

My numbers aren’t accurate but the room is the kitchen. It’s approx 4m by 4m.
The radiator is 10cm width and about 3cm from the wall so sticks out about 13-14cm. It’s about a metre and half long.
I have no idea what a trv is but the radiator gets pretty hot.

A TRV is a thermostatic radiator valve. It turns the radiator down, then off, once the room reaches its preset temperature. This reduces energy wastage, and means the top of the radiator is less likely to be scalding, unless the room is very cold and it has turned full on.

It is not used on the radiator in the room where the Wall Thermostat is fitted.

A radiator 100mm wide is probably a double. If a metre and a half long it might output in the region of 2kW of heat, which is reasonable for a room 4m square, depending on construction, age and insulation. A tall thin radiator is not as good at maintaining a comfortable temperature as a wide, short one.

You can get long, low radiators, even skirting-sized ones, that may be less of an obstruction, but you need the same surface area, and they are expensive to buy. There are hidden fan-operated versions that go under kitchen units, also expensive, and need maintenance to clean out dust and sometimes to repair the fans.

If you have wooden floors and don't mind them being taken up, you could have pipes run to a new radiator on a different wall. However kitchens full of units usually have little free wall space.

BTW the rated heat outputs you see in radiator catalogues are always overestimates, due to assumptions made in testing and calculation.

Thank you for all that info. Unfortunately, there’s no other wall and I really could do with that space as it’s the only space for a table.
It’s so annoying.

You might consider underfloor heating. It is expensive under a wooden floor, and very expensive if you already have a concrete floor.

Op have you looked into other heating options like rointe heaters they are very good

I would love underfloor hearing but it’s a concrete and tiled floor.
Any estimates of how much that could cost?

Mermaids thanks for that. I haven’t heard of that so will look it up.

This might seem counter intuitive but what about a radiator cover? I've a big rad behind my dining table and my main concern was dc burning on it whilst at the table. The cover, whilst taking up more room, has meant I can move the table closer to the rad as there's no fear of burning....if that makes any sense!?

if you already have a concrete floor, it is impractical unless you are very prosperous and whimsical. It means digging up the concrete and laying new. Noise and dust will be awful. Wet UFH is really only worthwhile adding if you are laying a new floor, either when building the house or building an extension. Some thousands.
