Best Electric Heater for a Caravan: Ceramic Heater Buyer's Guide

For most UK caravan owners on a hook-up pitch, a 230V ceramic fan heater is the right answer. It is cheap to buy, needs no fuel to carry, produces no combustion moisture, and can be sized to whatever your pitch supply allows. Gas has its place, but it is the answer to a different question.

This guide covers how to size an electric heater to your hook-up, what separates a good one from a cheap one, and where gas still wins.

Start with your hook-up, not the heater

A 230V heater's rating is the whole story, because it draws that load continuously while the element is on. At roughly 230V:

This is why the number of heat settings matters more than the maximum output. A heater with a single 2,000W element is unusable on a 10A pitch in practice, because you cannot turn it down to make room for the kettle.

The two models worth comparing

Ceramic Heater MKK-100

The MKK-100 runs at 230V with 750W and 1,500W settings, measures 19 x 17 x 26 cm and weighs 1.2 kg. It is the straightforward option: two levels, small footprint, low price.

The 750W setting is the useful one. It is enough to hold a small to medium caravan at a comfortable temperature once it is warm, and it leaves room on a 10A pitch for a kettle or an air fryer.

Ceramic Heater MKK-230

The MKK-230 has three heating levels, 500W, 1,000W and 1,500W, an adjustable thermostat, an oscillation function and fall protection. It measures 16.5 x 11.5 x 24 cm and weighs 1.1 kg, and runs on 220-240V.

The extra 500W step and the thermostat are what you are paying for. The thermostat means the heater cycles rather than running flat out, so the average draw over an evening is well below the setting you selected. On a metered pitch that is a direct saving. The oscillation spreads heat rather than cooking one end of the sofa, which matters in a narrow space.

What to look for in any caravan electric heater

• Multiple heat levels. Not for comfort, for electrical headroom. A single-setting heater takes your whole pitch supply hostage.
• A thermostat. Without one the heater runs continuously and you pay for heat you do not need.
• Tip-over cut-out. Caravans move, floors are not always level, and dogs exist.
• Ceramic element rather than a bare wire. Ceramic elements run at a lower surface temperature, which reduces the burnt-dust smell and the scorch risk.
• Small footprint. Floor space in a caravan is measured in inches.
• A fan-only mode. Useful in summer, so the heater earns its storage space year round.

Where gas still wins

Electric heating requires a hook-up. If you pitch off-grid, on a rally field, or at a CL without electricity, a gas heater is the only realistic option. Mestic's gas models run at 1.4kW, 2.8kW and 4.2kW on propane or butane at 30 mbar, which is far more heat than any 230V heater can deliver on a UK pitch.

The trade-offs are real, though. Burning gas produces water vapour, which in a sealed caravan in winter means condensation on every cold surface. Gas heaters need permanent ventilation, need a carbon monoxide alarm in the space, and you have to carry and change bottles. For a heated awning or a fully off-grid winter pitch that is a fair exchange. For a serviced pitch it is unnecessary work.

What it costs to run

All electric resistive heaters are equally efficient: every watt drawn becomes a watt of heat. There is no such thing as a more economical 1,500W heater in terms of heat produced per unit of electricity. What varies is how long the heater runs, and that is controlled by the thermostat and by which setting you choose.

Substitute your own site's metered rate. The important detail is that a thermostatically controlled heater does not draw its rated figure continuously. Once the cabin reaches the set temperature the element cycles off, so a 1,500W heater holding a warm van might average closer to 500W over the evening. A heater without a thermostat runs flat out for the whole four hours, which is why the thermostat pays for itself on a metered pitch.

Placement and safety

• Stand it on a hard, level surface, not on carpet or a rug where it can tip or block its own intake.
• Keep the intake at the back clear. Fan heaters pull air in behind and push it out at the front, and a heater pushed against a wall recirculates its own hot air and cycles off early.
• Keep at least a foot clear at the front, and never dry clothes on or directly in front of it.
• Do not run it from a coiled extension reel. Unwind the reel fully before putting a heating load on it.
• Do not leave a fan heater running unattended overnight in an occupied caravan.
• If you are using it in storage, check the site permits unattended heaters first. Many do not.

Sizing: how much heat do you need?

A touring caravan is a small, reasonably well-insulated box, and it will already have its own blown-air heating system. An electric fan heater is usually there to supplement that, to take the chill off in the morning, or to keep the van above freezing without burning gas.

For that job, 750W to 1,000W is sufficient in most touring caravans. Reach for 1,500W to warm the space from cold, then drop it back once it is up to temperature. Running 1,500W all evening on a 10A pitch is what causes both the tripped bollards and the surprising metered bills.
