Heating for tiny office

[John_S]

You could add a high tog underlay under the carpet.

I’m with Mr Pablo get an infra red panel heater in on the wall or ceiling and it’s instant warmth, might need two to ensure no dead spot under a desk but they are easy to fit can be mobile to do other duties in other rooms and low power.

No matter how many, wall- or ceiling-mounted, it's a cert that the knee-hole of the desk will be a chilly cave. I would go for warm clothes (including a hat) and a convector heater under the desk.
Does anyone remember the link to Japanese stoves which used to go under the table in otherwise unheated rooms, warmth kept in by a really thick tablecloth which hung down to the floor?

That is why I ultra-draped the dogs pen cage, being as there were 3 or 4 boxers at one time it was large & a bundle, with a heated mat for the one who preferred to sleep outside of the pen cage, with a roof of insulation extending out above it so inner heat of the cage would trickle towards her.

There was multi-foil insulation, & heavy fleece blankets as part of the construction, obviously I had a digital thermom under the slab too, their comfort was never in question, spoilt pups in as economic form as possible.

I would not like an air heater under there, maybe a tiny oil rad (400-500 watt thermostat controlled with offcut celotex type insulation reflector behind it, silent (except the thermostat click) when taking calls... & if the small office is akin to a small bathroom loo, sink combo likely that would bring up the entire space to a comfortable temp of 20-22c

Oops, starting to feel like an add for foam floor mats, but just remembered that we use them in another room, our small conservatory.

It's only about 2.4m by 2.4m, and has a tiled floor, but no insulation under the slab. When heating season arrives, I put down a floor of those black foam mats. The idea is that it will slightly insulate the floor, but also that the black will absorb more heat from the sun. Around April/May, when it warms up, I stack the pads on a shelf in the 'not garage'.

As Gus mentions, you can get packs very cheap.

A simple idea to hold back the radiated cold. Rugs are also a good way to layer up once carpet is down.

you will not feel warm working in a small brick type office until the walls are warm and not "radiating cold". If not occupied every day then you are faced with a cold office first thing which will only feel warm if lucky by the end of the day.

Therefore the choice is between a low constant heat like a oil filled rad permanently swiched on although it will have a thermostat or a instant radiant heater which will warm most of you and the surfaces feel warm quickly but soon as you switch it off it will cool quickly.

I would favour the latter for low occupancy levels.

Do not use a fan heater as this causes drafts and this makes it very difficult to feel warm (from experience)

Heat loss through the floor is only of the order of 15% but conduction through your feet to a cold floor can be uncomfortable, put a rug where you put your feet. Block of all draughts to your feet by for eg blocking off the back of desks. The cold air falling of the vertical surfaces causing draughts is no 1 problem. I can recommend a small oil filled rad under a closed off desk, keeps your lower 1/2 warm and heat trickles up to your upper.
