Why You Need Radiant Boilers For Hydronic Heating

Hydronic Heating

If you are interested in the installation of hydronic heating on your property, you might be wondering what you will need to power it.

This will occur via a radiant boiler, which is responsible for heating the water that is passed through the system (allowing the heat to pass up into the room beyond). There are a couple of boilers that you can choose from for your system, and you have come to the right place if your aim is to learn more about them.

Why hydronic heating?

The first thing that you need to understand is why people choose this type of heating in the first place. One of the main reasons is that it doesn’t generate dust around the home, keeping the space much cleaner and not aggravating asthma or allergies. These systems are also fairly unobtrusive (even if radiators have been chosen over underfloor) and won’t be an eyesore. They also operate almost silently, which is extremely handy if you have it on all night.

How do these boilers work?

Essentially, water is stored inside the unit (which has been installed on an external wall of your home) where it is heated to a temperature that you can predetermine using the thermostat. Once the water reaches the desired temperature, it is pumped out into pipes that run beneath the floor. The boiler can be powered using gas, oil, coal or electricity. The most common sources today are gas and electricity, as they are cheap and in abundance.

Firetube boilers

Also referred to as a shell boiler, this type is actually surrounded by water. The liquid is heated by the fire or gases burning within the unit; the hot gases are allowed to pass through the firetubes several times before being expelled. The tubes are usually set up at the banks of the unit and is able to release over 11,000 kilograms of steam per hour. This type actually makes up around 80% of the boilers that are in use for these heating systems.

Watertube boilers

The heating tubes in this type are arranged vertically in a water-filled shell. Most of these boilers are rectangular in shape and have two drums that are arranged at the top and bottom – the top one separates water and steam, whilst the bottom one collects sludge. These units are quite heavy duty and are generally used when more heat is required – they are known to generate temperatures of up to 1160 degrees Celsius before being circulated.

Do they need to be maintained?

It is essential that you regularly check your boiler and ensure that any excess pressure is not built up. To check the pressure, run the unit for short periods of time and see how much has built up during each time – does it decrease or increase? On top of this, the boilers have to be maintained regularly to ensure that they remain in tiptop condition because the amounts of steam and heat that can be generated have been known to cause premature wear.

Now that you are aware of the different boilers that you can choose for your hydronic heating system, you should be fully prepared to arrange your installation and answer all of the pertinent questions. Just make sure that your unit has been properly cared for, as this will ensure that it remains in tiptop condition for many years to come and that your home will be provided with the level of heat that you desire during those cold winter months.
