Heating Units for Heating Systems
Tailored Heating Solutions
Collin’s Plumbing offers tailored heating solutions for your home. Find out below the types of units we work with.
Although we do enjoy the Bosch product range, our plumbers and gas fitters can also design and install tailor made systems to suit any type of heating unit. Our energy efficient heating systems include:
- Ducted gas central heating
- Bosch air to water heat pumps
- Bosch ground source heating
- Bosch gas boilers
- Solid fuel boilers
- Underfloor heating
- Ceiling and wall panel heating
- Pool and spa heating
- Under floor heating
- Diesel boilers
- Waste oil boilers
- Wood pellet or chip boilers
- Coal boilers
- Solar heating
- Hot water cylinders
- Fan coil units
- Ducted air heating
A Ground Source Heating Unit uses energy from the ground that remains rather constant, even in colder areas in New Zealand.
This energy from the ground is transferred from the earth to the water/ glycol mix that runs through pipes that are buried under the ground. They can be buried within trenches or boreholes drilled down into the ground. This pre-heated fluid runs to and through a Heatpump Unit that exchanges the energy to the heating systems that will then be used directly for potable hot water and space heating/cooling.
A Ground Source Heatpump has pipes that can also be placed in water such as a lake or river if this is available nearby the dwelling to be built.
This Ground Source Unit and the boreholes sizing and depth is all part of the calculation that takes place as part of the Heat Retention Calculation has been carried out.
Features of Ground Source Heating Unit
- Quiet running inside, external unit runs with a quiet fan.
- Exceptional cost reducing running costs, up to 75% of your hot water for free.
- Set and forget installation, has a built in brain.
- Can be used for potable hot water and heating systems.
- Can be used to cool depending on the type on componentry you have installed in the dwelling.
- No outdoor componentry, great for areas where salt air corrosion could be an issue.
There are many types of gas boilers. They run from reticulated or LPG bottles to heat water that is then used to give both potable hot water and hot water to run through a heating system. The conventional or system boilers have to be used in conjunction with a cylinder to store the hot water in.
The Combination Boiler provides hot water for potable and also hot water for any hydronic heating requirements. The Gas Boiler size is determined by the Heat Retention Calculation and the requirements of the usage.
The Combination Boiler is designed to capture and recover the energy that is normally discharged into the atmosphere. When working at its top efficiency, the water vapour produced by the burning of gas condenses back into liquid water. The boiler uses a heat exchanger so that the incoming water cools the exhaust forcing condensation of the water vapour it contains; this has the effect of preheating the water.
Features of Gas Boilers:
- Can be used to provide heating and potable hot water.
- Very efficient in running costs
- Small units space saving.
- High water temperatures produced.
- Efficient in either warmer or cooler climates.
- Price of running is constantly dependant on the price of gas and availability.
Diesel boilers burn Diesel to heat the hot water that then is used for heating and potable hot water. The choice of diesel boiler usually comes down to personal choice but also the availability of fuel to the dwelling location. The diesel boiler size is determined by the Heat Retention Calculation and the type of demand that is needed.
There are now Condensing Diesel Boilers, which offer a better fuel efficiency in their usage. They have great control safety and performance features. The diesel storage tanks are usually of a twin skinned nature to ensure no diesel leaks, to capture any leaks even if there is one.
- Very efficient in heating hot water
- Creates hot water for potable use as well as hydronic heating systems.
- Can be used to burn Bio-fuels.
- Flexibility leads itself to isolated locations of dwellings.
- Requires Diesel storage.
- Running cost is dependent on Diesel costs and availability, and of course usage.
