Underfloor Heating & Hot Water Heating
Hot Water Heat Pump Systems (Underfloor & Potable water)
Our range of Underfloor Heating and Hot Water Heating heat pumps can provide heating of hot water for both underfloor, wall radiators or potable water cylinders.
With extremely good energy efficiencies these systems work particularly well in underfloor situations and should be seriously considered when building. Often the same size heat pump can also provide your potable hot water needs when coupled to our optional hot water cylinder.
The system comprises an outdoor unit which couples to an indoor hydro box and valve panel or to the optional hot water cylinder. Both of these can easily be accommodated in the garage or laundry areas.
Heat is extracted from the outside air to heat the water in the hydro-box which then pumps it to either the underfloor system or hot water cylinder.
The secret to any good underfloor system is the spacing of the water tubes in the floor. At Hartnell Coolheat we always base our design on 150mm centres. Whilst wider spacings are possible it has been our experience that whilst reducing the price the wider spacings do not offer the same effective heating as the closer spacing does.
Further adaptations allows this system to couple to a ducted indoor unit to not only provide winter heating but also summer cooling.
This is truly a universal heating system.
Atlantic Hot Water Heat Pumps
We are Dealers for the French-made range of Atlantic Hot Water Heat Pumps for heating of potable water. These are a self-contained 270 litre unit comprising tank & heat pump in one neat package. They can be installed in laundry or garage and are complete with exterior wall venting kit. Not only can they heat your hot water at a fraction of the price of a normal electric cylinder but also provide extraction ventilation of the space they are located in.

Heat Pump Air Conditioning
Heat Pump Air Conditioning Systems
There are a few standards to check when buying a heat pump. Two of the main signs to look for are if the unit is MEP’s compliant and also has the ‘C-Tick’. If they are MEP’s compliant it means they have reached or exceeded the Minimum Energy Performance Standard necessary for sale in New Zealand and are registered with the EECA (the Energy Efficiency and Conservation Authority).
The heat pump should also display the industry standard ‘C-tick’. This mark shows that the unit meets the New Zealand requirements for Electromagnetic Compatibility. It pays to check for this mark as unlabeled products can interfere with radio and television reception and potentially cause problems for the communication systems of emergency services
Heat Pumps are the most cost efficient heating and cooling systems available on the market
Specialized Applications (Heat Pump, Heat Recovery, Ventilation & Air Conditioning Systems)
Swimming Pools
Hartnell Coolheat undertakes specialized ventilation and heating for enclosed swimming pools and water heating. We utilize the NZ-made Temperzone hot water heat heat pump range of equipment for the best of results.
Clean Rooms
Clean rooms require the highest level of ventilation and filtration demanding specialist equipment which we are able to offer in the form of European manufactured equipment.
Process Cooling
To ensure equipment or computer rooms are kept at an accurate temperature we can design precise climate control systems using either the Stulz or Liebert range of equipment.
Heat Recovery and Ventilation systems
Heat Recovery Ventilation systems (HRU or HRV) and Mechanical Ventilation Systems
Basic description of Heat Recovery System:
HRU Systems are designed for both energy saving and improving indoor air quality. Using air-to-air heat exchangers, they are able to work with a range of residential, commercial and industrial applications.
These Heat exchangers can be used in conjunction with Air Conditioning / Heating systems archiving efficiencies of up to 85% when transferring heat from exhausted air to incoming outside air.

We offer a range of mechanical ventilation solutions for your requirements.
On both commercial and residential projects bathroom, toilet, laundry and kitchen are key areas requiring ventilation. This is becoming more frequent in recent times as many new buildings, especially in the commercial sector, are now constructed with fixed window placement. With this design feature there are a number of different regulations to take into account within the New Zealand Building Code.
With ductwork, fans and filtration systems fresh air can be transferred, smells can be extracted and heat can be moved from one area to another. A well-ducted ventilation system is therefore paramount in providing a comfortable and healthy interior environment.
