Plinth Heaters Buying Guide

Heating your utility rooms and kitchen should be part of your priority when looking for heating solutions for your home. But most people often neglect it. Just as an electric log burner is best suited for living rooms, and conservatory heaters for conservatories, a plinth heater works best in kitchens.

You could also use a baseboard heater, oil filled radiator, or fan heater, but they are not as compact as the plinth heater. You can also control it using a wireless thermostat, depending on the model you choose. We will guide you through picking the best plinth heater in the market.

Important Features to Consider Before Buying a plinth Heater

Important Features to Consider Before Buying a plinth Heater

Before you buy a plinth heater, it's essential to consider the size of your kitchen. You want to buy a unit with the right output for your space. Another thing you need to consider is the decibel level. How noisy is the device when at work? If you have a large kitchen with the need to have the heater on all day, it means you will have to come to terms with whatever noise it makes all day without going bonkers.So you'll have to consider the noise level seriously.

Whether the heater ishydronic or electric is not a crucial factor as both hydronic and electric heaters have their upsides and perhaps downsides too. However, it may be best to go for a dual fuel model if they come within your budget. The dual models are the best units to have since they offer the apparent two-in-one advantage. But this is not a deal-breaker. 

What is a Plinth Heater?

A plinth heater is a heating device that serves as an excellent alternative to a radiator.It is designed for kitchen use and utility rooms.

A plinth heater has an advantage over a radiator in its compactness. It can help you save space. As we mentioned already, it doesn’t take up any active area in your kitchen since users often install them in hidden spots under furniture and counters in the kitchen.

Plinth heaters come in three forms. There is the hydronic type of heater, and then there is the electric type and lastly, the dual model that combines both forms. Even though these devices produce heat as soon as they are switched on, they do not get hot to touch, which is helpful, especially if you have little children in your house with their restless selves.

You can install these units at home or in a commercial building. But as we said, they are mostly installed in kitchens where there is often little or no space for a wall-mounted or free-standing radiators or electric wall heaters anyway.

A plinth heater can either power itself (electric units) or can be powered by the central heating system in your home.The electric units are connected to the mains electricity to power the fan that pushes out the hot air into the room.

How to Use a Plinth Heater

To use a plinth heater, you must first install it.

Having installed it, you flip the switch and turn on the unit.

Set the heater switch to the red disc position.

Then choose whether you want the fan in Low or Boost.

Provided there is hot water circulating through the heat exchanger; the fan will start to spin.

Some models heat quicker than others.  Also, if the central heating system has just been switched on the fan may delay starting until the system boils to 43 degrees C.

The fan automatically stops when the central heating system goes off, and the system temperature drops.

Benefits of a Plinth Heater

When it comes to the benefits of these units, it's a full menu.

In case we haven't been clear enough, one significant benefit of a plinth heater is that it saves space. When space is tight in your bachelorpad, for instance, the last thing you want is to choke yourself further by installing a traditional radiator. And this is where the plinth unit comes to your rescue.

They say repetition is the mother of learning, so let me repeat it. One primary benefit of the plinth heater is that you can have it tossed (installed) behind your kitchen counter. It’s not going to ruin your kitchen design or cramp your style in any way.

However, that these heaters are small does not affect their effectiveness. They will heat your kitchen with enough heat left to spare for nearby areas or even your home garden. If you get a good model,like the Thermix KPH 2100 or the Smiths Space saver, your guests will be so impressed by the unimposing efficiency of your plinth unit that they will get theirs in a hurry.

Another benefit of the plinth heater is that it produces heat without being hot to the touch. Therefore, the plinth heater is a safe option that doesn’t pose any danger to unattended children.

An additional benefit is that the best plinth heaters are economical to run. They can cost you as little as 3p per day to use.

Also, you can install them quickly, and they're easy to use, as you may have noticed from my how-to-use explanation.

Finally, plinth units come in a variety of finishes which you can select from based on your kitchen style and design.

So, as you can see, there are several benefits to installing a plinth unit. It's a space saver that won't devour your precious wall space. It’s a fantastic alternative to traditional radiators for heating a room. It can be installed in a hidden corner, to work virtually invisibly and they are manufactured in such a way that they add some style to your entire kitchen décor. And they are easy to install and cheap to run and use.

Plinth Heaters Buying FAQs

Q: Are plinth heaters any good?

A: Some say plinth heaters are as good as radiators. Others say they're a less reliable option, but everyone agrees that they are more reliable than a cooker extractor. What do I say?

I say, search out a right plinth heater and see things for yourself.

If they are a lot cheaper than underfloorheating and less upsetting to your room settings, they are much useful. If they don’t take up any active space in your kitchen and heat the place quicker than any radiator would, they are much helpful.

The major complaint many people have with plinth units is their noise. We will talk about this in a moment. Also, some folks think these little heaters are overpriced being costlier than any simple radiator. I think those folks are much mistaken.

When dust collects in the heater, particularly after long periods of not being used, it will give a burning smell when you first use it again. This smell is neither dangerous nor long-lasting. However, always try to keep your unit as dust and particle-free as possible

There’s no denying the fact that getting your toes warmed while doing laundry on a cold winter evening is a thing of joy! So, in answering the question, I’d say a big YES. The best plinth heaters are certainly a valuable tool to have in your home.

Q: How do hydronic plinth heaters work?

A: Hydronic has to do with 'hydro' which has to do with energy derived from water. Therefore, a hydronic plinth heater works with water- hot water. A hydronic heater uses its in-built heat exchanger to generate heat from the central heating system. The heater is connected to the pipes of the central heating which the fan convector blows air over till they are warm and then it blows hot air into the room.

As a Quora user described it, 'picture an old steam radiator laid down flat on its side and fitted under your kitchen cabinets, at floor level. Add a fan to this, to help circulate the heat, and you have a hydronic plinth heater.'

Q: Are plinth heaters noisy?

A: Many manufacturers of plinth units refer the buyer to the noise levels of the device. However, if you own a great plinth heater, you will agree that these units make a humming sound that can,at best, be likened to a working fridge and, at worse, to a working oven.

So my answer to this question is that a good plinth heater is no noisier than a fridge is.

Is that too noisy for you?

Q: What does a plinth heater do?

A: A plinth heater provides heat for your kitchen or laundry. Some of them have strong outputs that can circulate to other nearby rooms escaping through open doors.

It comes as anelectric plinth heater, hydronic plinth or dual plinth model. They produce heat as soon as they are switched on; some models more quickly than others. Many plinth units also have built-in overheat protection. They are mostly safe devices to have around the home.
