Central Heating

Central Heating Systems – Design And Installation

If you are sick of living in a home colder than the outside temperature  – you need central heating. Long gone are the days where it was only accessible to those with extreme wealth. Central heating is an extremely effective, efficient and healthy way to heat your home and Hamilton Plumbing services all of the Waikato designing, installing and maintaining central heating systems.

WHAT IS CENTRAL HEATING?

It is a way of heating your home using warm water or air which is circulated throughout your home using pipes installed in the concrete floor or through wall-mounted radiators.

You will find that most Central Heating systems can also heat your hot water, and therefore help reduce your energy costs.

Central Heating suits most homes. We work with you to develop a system tailored to your buildings particular requirements, taking into account the size of your home and availability of gas services in your area. We can offer solutions for both new and existing dwellings.

Types of Central Heating

When considering central heating, Hamilton Plumbing can help you weigh up every option and get you the best system for your home and lifestyle.

 Ducted Central Heating

The air inside your home is heated by a gas furnace heat exchanger.  The warmed air is then delivered to the room in need, via flexible insulated ducting.  The exhaust gases from combustion are flued out of the home, so you are not left with any condensation.

Hydronic (Water) Underfloor Heating

Hydronic underfloor heating is a permanent central heating option as it is built into concrete or screed floors. It is not suitable for retrofitting projects (where central heating is installed in an existing home). Many types of floor finish can be overlaid including wood, stone, tiles, vinyl or carpet, though careful consideration is needed to ensure it will not be affected by the heat and/or will not insulate against it.

Hydronic underfloor central heating provides many benefits such as:

  • Super energy efficiency – natural gas is cheaper than electricity
  • As naturally heat rises – it is a logical heating solution
  • Concrete slabs produce radiant heat long after you turn off the source of the heat;
  • Hydronic underfloor central heaters can have room-by-room controls. This allows you to only heat the rooms you are using.
  • Low maintenance – nothing to dust or clean.

Radiators

Long gone are the ugly systems you remember from your childhood. Radiators have come into their own recently and are now available in a number of designs and are even paintable to fit your décor.

There are two types of radiators on the market – Hot Water and Steam.

Hot Water Radiators: These radiators takes hot water in and keeps it hot  – never to boiling point – and then an outlet lets the water back out. After the water reaches the desired temperature it is pumped from the heater to all of the radiators in the system. The heater and pump are typically tied to a thermostat so they know when to kick on. That ensures that they are only operating when heat needs to be provided to the rest of the home.

Steam Radiators: Steam radiators are connected to a boiler which heats up water until it forms into steam. The steam then travels up through a vertical pipe to the radiator where the thermal energy is given off through the fins. As the heat is lost from the steam, it slowly begins to turn back into water. Eventually the steam becomes water and flows back down into the boiler for heating once again. The cycle repeats over and over again in order to spread heat to the rest of the home.

Air Source Heat Pumps

Air source heat pumps absorb heat from the outside air. They are efficient at heating even when the temperature is as low as -15° C. An air source heat pump will heat your home as well as your water. They have minimal maintenance requirements and can be easier to install than a ground source heat pump.

Thermal Stores

A thermal store is a way of storing and managing renewable heat until it is needed. Heated water is usually stored in a large well-insulated cylinder often called a buffer or accumulator tank. It may also include an electrical heating element, such as an immersion heater. Thermal stores have proved to work particularly well with wood-fuelled biomass boilers, heat pumps, wind energy and solar water heating systems. A thermal store allows for the management of the difference in time between when heat is available and when it is needed. For example, hot water produced by a solar water heating system during the day can be stored for use when little or no solar energy is available.
