Buyer’s Guide

Plinth heaters can be electric or hydronic depending on the heating system that you have at home. The best hydronic plinth heater will synchronise with your hot water heating system to provide heat optimally. It makes matters easier because one can control the amount of heat released through the central heating system.

Electric plinth heaters rely on electricity and a fan to distribute heat. These types of models are plugged in independently, therefore, feeding off direct electricity, unlike the hydronic heaters. The best electric plinth heater will provide consistent heat without hiking up your electric bill.

Heat settings

Heat settings give the user control over how much heat is released into the space. Some models come with one heat setting and others offer 2-3 settings. A plinth heater with one heat setting is great if you want the kitchen to remain at a certain temperature at all times. If you require less heat during the summer then a plinth heater with various heat settings is recommended.

Indicator

A model that would make the best heater for underneath kitchen units needs an indicator. An indicator acts as a signal to show whether the heater is running or it is off. This removes the need for guesswork, especially with models that feature remote control. The CDA APH01SS Plinth Heater is a good example of a model with a visible indicator.

Thermostat 

A thermostat prevents overheating and it saves energy. When you select a heat setting, the best plinth heater will have a thermostat to shut down any further heat production once the required temperature is attained, saving energy and money. There are models, however, that do not come with an internal thermostat because they rely on the central heating system for temperature control.

Timer

A programmable timer permits the user to select periods of the day or week when the heater is to run. Admittedly, not many models provide this feature but some do. If you require the kitchen to be warm at specific times then you will require a plinth heater with a detailed timer.

Size of the kitchen

The size of the kitchen determines the size and quantity of plinth heaters to get. If you have a small kitchen then you do not need a plinth heater designed for industrial kitchens. If you have a large kitchen that is well ventilated you will require several models or one large plinth heater. Manufacturers usually specify the maximum room size the heater will serve comfortably.

Installation

When you select a plinth heater with a grill that you like, you have to also see if it will fit the area of installation. Sometimes manufacturers provide inaccurate installation measurements so it is prudent to take your own measurements. This is important so that you don’t make any mistakes and have to replace the plinth. 

Take into account the size of the plinth when you are shopping for a suitable plinth heater. You can give yourself an extra margin of a few inches to contain any errors made during installation.

Warranty

Many plinth heaters come with a warranty, therefore, that should not worry you. The difference is in the length of the warranty. A longer warranty assures you that the quality will last for longer compared to a model that offers a 1 year warranty. Be sure to read the terms and conditions of the warranty to avoid back and forth with the manufacturer just in case something goes wrong.


FAQs

How are plinth heaters better than radiators?

It is unfair to compare radiators and plinth heaters because they are giants in their own rights? A radiator is awesome for heating large spaces but it takes up space whether left freestanding or mounted on a wall. Plinth heaters also heat spaces and they take up little space making them suitable for areas that are tied down for space. Plinth heaters are preferred for kitchens because they take up little space in the kitchen that is already filled with plenty of equipment. 

Are plinth heaters generally noisy?

Plinth heaters that bear fans with different settings will most likely be a little noisy. Many people are aware of the noise when the fan is on its highest setting. Some models operate more quietly than others so always check the product description and customer reviews for a better insight.

Which is better? Hydronic or Electric?

This depends on the heating system that you already have. Hydronic plinth heaters do not run up a huge bill because they rely on the central heating system to distribute the heat although they do usually also need wiring into a fused spur too for the fan and controls.

Electric models are perfect for occasional use because they can be turned on and off as required and if you don’t have a central heating system in the kitchen it saves rerouting the central heating pipes. This all boils down to personal preference really because the best electric plinth heater and best hydronic plinth heater will have something to offer to each kitchen.

I would say that if you have easy access to the central heating pipes use a hydronic model and make use of the water that is already heated and pumped around your home.


Final Conclusion

There is no debate that plinth heaters make kitchens a cosier place to be, especially if your family hang out there a lot. Selecting a suitable model will revolutionise how you experience those winter days. 

For example, the best plinth heater in this review is the Smiths 2kW Electric model because it not only warms the kitchen effectively, it is accompanied by a 5 year warranty hence you can be confident it will last just as long.

Our runner up model, the Bidex Diamond 500 Plinth Heater, warms a larger area than our best pick and it is easily connected to the central heating system. 

All in all, it is possible to find a plinth heater that will cater to your type of kitchen. Our advice is to consider all the features offered and pay a price that you can afford in the long run.
