Manual Vs Thermostatic Heating: What to Choose?

Manual heating

This is the most basic method of controlling your home’s heating. The heater is a manual valve and operates similarly to a regular water tap. You can adjust the bathroom’s temperature by turning the valve on and off.

The only disadvantage of manual heating is that it requires constant monitoring. You may have to ensure that the bathroom temperature is neither too hot nor too cold. This is best suited for:

  • A less frequently used bathroom
  • A location with substantial low temperature

Thermostatic heating

This heater works with a Thermostatic Radiator Valve (TRV). It has a temperature sensor built in to keep the temperature in the bathroom consistent. This is best suited for:

  • Frequently used bathroom
  • Areas where the temperature lowers rapidly in the winter

Bathroom Radiator

Types of Bathroom Heaters

Based on your budget and preferences, there are three main types of bathroom heaters:


Bathroom radiators are the priciest bathroom heating option. However, their elegant design and superior performance often justify the higher cost.

How to Choose a Bathroom Heater?

Before deciding on which bathroom heater to buy, it’s critical to understand that a bathroom is divided into four distinct zones. These zones are determined by the risk of water coming into contact with an electrical source.

The 4 zones are:

  • Zone 0: The region inside the bath or shower basin may hold water.
  • Zone 1: It’s the area right above Zone 0; your bath or shower may be just 2.25m high. It excludes Zone 0.
  • Zone 2: It’s the area where Zone 1 enlarged to 0.6m vertically and horizontally around the bath or shower.
  • Zone 3: This is the water-free zone.

Now, since you know the basics, it’s time to consider the other factors while choosing a bathroom heater.


Since many bathrooms are compact, it’s vital to utilize the space wisely. Hence, examine your bathroom’s layout. You don’t want a heater that takes up half the room or have it be too close to the zones above. Thus, a wall-mounted heater is preferable. It eliminates most of the issue and take up very little space.


When it comes to durability and long-term performance, it’s essential to look for the product’s reliability. It is suggested to check:

  • The waterproof rating
  • The need for maintenance
  • Wattage and heating capacity
  • Safety features
  • Energy efficiency
  • Aesthetics

It’s advisable to go with a reputable company that will provide you with after-sale service, and help you with the installation process.


Bathroom heaters are generally cost-effective as compared to other heaters in your home. If you don’t want to invest in your current home, plenty of cheap temporary fixes are available. You may opt for the less efficient ones and serve the purpose.

Long-term homeowners may wish to consider a modern wall-mounted system that requires less maintenance and offers adequate heating.

Consider installation costs for each heating option. For example:

  • A heater that uses central heating would require a plumber to install
  • An electric underfloor heating is better installed during construction to avoid costly refurbishments


Safety precautions

While you’re eager to begin enjoying a warmer bathroom experience, it’s also critical to incorporate specific safety considerations. Follow the basic recommendations below, and you can safely enjoy the experience.

GFCI protection

The first safety precaution is using ground-fault circuit interrupter (GFCI) outputs.

If there are tiny changes in current, these safety outlets will immediately switch off the electricity. However, it’s best to get the upgraded version and double-check it with your retailer.


While installing your bathroom heater, it is critical to pay attention to the zones.

It is also worth noting that, while these bathroom heaters can manage water vapour, they may not be able to handle dense fluid water. As a result, their positioning is crucial.

Prefer wall mounted

Wall-mounted heaters are preferable in bathrooms. If any other system bursts or leaks, you’ll have to pay for a costly new installation. Wall-mounted electric radiators not only don’t have these concerns, but any repairs are quick and easy. So, they minimize the hazards.

Air your bathroom

By ventilating your bathroom, you safeguard the electronics in your heater from wear and tear.

Airing out your bathroom regularly may theoretically be even more efficient, as heat prevents water condensation. If you don’t have any windows, use ventilators.

Wet towel covering

This is the most fundamental tip of all. It is suggested not to cover your radiators with wet towels. Aside from that, putting wet towels over a radiator insulates it and inhibits it from adequately circulating. This will impact convectors, which operate by creating hot air currents and will be significantly less effective.


An excellent bathroom heater will last longer and come with a warranty, so you won’t have to worry. However, it will be helpful if you remember the above suggestions.

There is a bathroom heater for everyone’s needs. So, if you appreciate those warm mornings in the bathroom, choose one that works best for your setup and say goodbye to early morning chills!
