Hydronic Heating Technology

Hydronic Heating

Hydronic heating uses hot water as a heat transfer medium. A boiler or heat pump transfers its heat to water which is then circulated to heaters throughout the home to provide the most comfortable form of heating possible. These heaters can be radiator panels, towel rails, fan coil units or through in-floor heating. This gentle, silent, radiant heat does not scatter dust, mites or other allergans.

Hydronic heating systems are installed during the construction phase or can be retrofitted to existing buildings.

Benefits

  • Hydronic Heating Systems are cleaner and quieter
    A properly designed hydronic system is comfortable and non intrusive.
  • Hydronic Systems Are Quiet
    With relatively few moving parts hydronic heating is virtually silent within the house.
  • Hydronic Systems Are More Durable
    A hydronic system will ordinarily serve 25 years or more, both because of the material used and the minimum number of moving parts.
  • Easy Zoning Your Home For Maximum Comfort
    There is no one temperature that is comfortable at all times. A hydronic system can be installed with independent temperature controls known as zones for any area of your home, or specific rooms,that work automatically. bedrooms can be kept cool for a restful sleep, while bathrooms are warm for a comfortable morning shower.

Heat Source

The heat source for heating water for the system can be provided by a number of options - gas boiler; solid fuel or oil boiler; heat pump; geo-exchange; active solar

Heat distribution

heatingThe water heated by the boiler is circulated throughout the building to either radiator panels, floor coil, towel warmers, or fan coil units. Radiator Panels work by heating the air which flows past them. Warm air rises from the radiators and colder air in the room falls. This circulation develops a flow of air around the room sending warm air from the radiator and delivering cooler air back to be heated. So, for radiators to work well there must be adequate clearance around them so that air flow isn't restricted.

Radiators are selected according to the output you require

Underfloor slab heating is one of the oldest types of central heating. A modern slab heating system works by circulating warm water through pipes laid in loops and embedded in the concrete slab or screed laid on top of the slab. The surface area gently radiates heat upwards and evenly into the room. Virtually any type of floor covering, such as tiles, stone, marble and specified timber floors can be used.

  • Benefits of underfloor slab heating
  • Gentle heat with typical Typical floor temperatures 27-28C
  • Economy
  • Low water temperature heating ideal for condensing boilers and heat pumps.
  • Design
  • No restrictions on furniture placement. The heating system is hidden beneath your feet allowing complete freedom with interior design
  • Full height glazing is no longer a problem
  • Maintenance

Heating controls

A major advantage of hydronic heating systems is in the amount of control available to you. Heating zones can be created for your home. Comfort can be further enhanced by enabling each room to be controlled individually using thermostatically controlled radiator valves.

What is a programmer?

Programmers allow you to set when the heating and hot water come 'On' and go 'Off' again. By installing a programmer, and heating your home only as and when necessary, you will save energy and money.

A programmable room thermostat lets you choose the times you want your home to be heated and the temperature you want it to reach while it is on. In other words, it allows you to heat rooms or the whole house to different temperatures in your home at appropriate times of the day and week.

What are thermostatic radiator valves (TRVs)?

TRVs sense the air temperature around them and regulate the flow of hot water entering the radiators to keep a set temperature in a room. Again, they can help you save money and energy - by allowing temperatures in some rooms than in others, and to turn off the heating in rooms that aren't used.

In the majority of cases TRVs can not turn off the boiler when the whole house has reached the right temperature. To do that, you will need a room thermostat as well. Radiators in the space containing the room thermostat should not normally have TRVs. But if they do, you should keep the TRVs on their highest possible settings, and set the room thermostat to the required temperature instead.
