Plinth Heater

What is a Plinth Heater?

A plinth heater is a small, letterbox shaped heater that fits neatly into the bottom of your kitchen or utility counters. They are designed for those who don’t have the wall space for a bulky radiator, allowing you to maximise your kitchen space without sacrificing on heat. 

They work thanks to their large surface area, in the form of a grill. Boosted by an optional fan, they can deliver an instant high load of heat directly into your room quickly and efficiently. 

There are two types of plinth heaters available. These are:

The first of these is rather self-explanatory. An electric plinth heater plugs straight into a mains electricity supply, making them incredibly easy to set up. Heat is generated electrically while a fan circulates it around the room. The downside is, of course, that they will run off your electricity supply, which can make them more expensive to run. 

The second option is a hydronic plinth heater. These are plumbed into your central heating system, so work similarly to a radiator; they receive a flow of hot water which is then helped distributed into the room with a fan if required. While a hydronic plinth heater isn’t as quick to install as an electric version, they are usually more cost-effective to run, if you have a gas boiler. 

Are Plinth Heaters Expensive to Run?

The answer to this question depends on what type of plinth heater you buy. Electric plinth heaters are usually more expensive to run than hydronic heaters, as they run independently from their own source of electricity. As electricity generally has a higher cost per kilowatt, to run any heater with electricity usually costs more than gas.

Since most homes already have a gas boiler and radiator system set up, the running cost of adding a hydronic plinth heater won’t be excessive at all. However, be aware that some models do include an electric fan to help distribute the heat, which will add a small additional running cost when it is switched on. Many of our central heating plinth heaters at Plumbworld include a handy thermostat which only switches the fan on for you when it is most efficient to do so.

Are Plinth Heaters Noisy?

One question we hear a lot about plinth heaters is about how noisy they are. The sound being referred to is the noise made by the internal fan that helps push the heat into the room.

However, the amount of noise plinth heaters make generally shouldn’t be a cause for concern. We’ve heard many people describe the noise level as being similar to a fan oven or fridge operating - which shouldn’t be too bothersome in a kitchen! In fact, with a hydronic plinth heater, you don’t necessarily need to have the fan running constantly, so you can reduce the sound disturbance to zero!

Which Plinth Heater is Best?

At Plumbworld, we stock some of the best plinth heaters from leading brand names, Myson and Smiths. 

The best Myson hydronic plinth heaters feature a useful low limit thermostat, which activates the fan only when the water temperature reaches 43 degrees celsius, helping to control power consumption.

Many of Smiths’ best plinth includes both a hot and cold fan setting, so you can also use it to help cool the kitchen down when it starts getting too warm - great for when you’ve been cooking for a few hours! Their low voltage models are also suitable for use in high humidity areas, such as bathrooms.

All of our plinth heaters also boast easy to use controls and interchangeable grills, plus a guarantee to protect you if something breaks. So, be sure to come to Plumbworld to find the best plinth heaters at low prices!

How to Install a Plinth Heater

To install a plinth heater correctly, all instructions provided in the product manual must be followed. In most cases, installing a plinth heater is not a simple DIY job; hydronic plinth heaters will usually require a certified plumber to deal with the pipe and electric connections of the fan.

However, here are the steps that will usually be taken to install a hydronic plinth heater:

 

  • Cut an opening in the plinth. This will be at the bottom of your kitchen counters, below the doors. There will usually be some clearance space required around the heater to provide an airflow. It must be placed on a flat and stable surface. 

  • Fit the isolating valves. These might not be provided with your heater. The flexible hose pipes will then need to be connected from the heater to the central heating system. 

  • Connect electrics. Isolate the electricity supply. Plinth heaters are classed as a fixed appliance and electrical connection should be via a double pole 3A fused spur with a minimum contact gap of 3mm. 

  • Position the heater. Ensure no cables or hoses are kinked or snagged. 

  • Fix to the plinth. The grill can now be fixed into place on the plinth with screws.

  • Follow manufacturers instructions to complete the set up. Now that the heater is in place, you will need to adjust the settings as required.

Please note that this is only a general guide. All safety precautions and regulations must be taken, so it is best for a qualified professional to carry out this job.

How do I decide between a hydronic plinth heater and an electric model for your kitchen or utility?

Hydronic plinth heaters connect to your central heating and are generally more cost effective to run, which is why many people who already have a boiler prefer models from Myson and Smith's. Electric plinth heaters, such as Smith's SS80E or the Myson 500E Eco, work independently of your central system and suit homes without wet central heating or where you want localised warmth. If you want to heat the room only occasionally or don't have pipework to hand, an electric model is simpler; if you want lower running costs through the winter, choose hydronic.

What dimensions should you check so a plinth heater fits neatly into your kitchen units?

Measure the plinth height, width and depth of your cabinet void and match those to the product ranges shown here heights commonly sit in 51–75 mm, 76–100 mm or 101–125 mm bands, widths frequently range from about 450–649 mm, and depths are typically between roughly 249–355 mm. For a standard 600 mm base unit you'd look at 600 mm models such as the Myson Kickspace 600, while a narrower 500 mm unit suits Myson Kickspace 500 or similar Smith's models. Also allow a little clearance behind the grill for airflow so the heater performs efficiently.

How much heat do plinth heaters give and how do you choose the right kW for your space?

Plinth heaters on this site list outputs in bands such as 1–1.5 kW, 1.6–2 kW, 2.1–2.5 kW and 2.6–3 kW, so you can match output to room size and heat loss. Small utility rooms or cloakrooms often need around 1–1.5 kW, a typical galley kitchen 1.6–2.5 kW, and larger open-plan kitchens or replacing a radiator might need 2.6–3 kW or a dual unit like Smith's SS5 Dual. If you're unsure, pick a slightly larger output rather than undersizing, because underpowered units will struggle to maintain comfort.

Can you change the look of a plinth heater to suit your kitchen design?

Yes, many models offer interchangeable or optional coloured grilles and finishes, including brushed stainless steel, white, black and overlay grilles for a tailored look. For example, you'll find Myson and Smith's grilles in brushed steel or black and spare grilles sold individually if you want to refresh the finish later. Choosing a stainless brushed grille gives a contemporary feel, while a black overlay can create a striking contrast against light cabinetry.

What control options are available and which will make running the heater easier and more efficient?

Controls range from simple manual switches up to remote and wireless systems, for instance, Smith's wall-mounted control switch, Consort wireless PHSL series and Smith's EasiLink wireless kit with controller. A thermostat-controlled wireless kit lets you set schedules or a desired room temperature so the unit only runs when needed, reducing wasted energy, whereas manual control is simpler but can be less economical. If you want hands-off convenience and better efficiency, a wireless or remote control paired with a thermostat is a sensible choice.
