Heat Transfer Systems NZ - Get The Most Out Of Your Woodburner - 07/07/2017

Are you making the best use of your heating, or do you find the warmth is mainly confined to one or two rooms? For example, many people have log burners, which make the living space warm and cosy, but this heat is often disappearing up into the roof space rather than being transferred to other areas of the house.  

Heat transfer systems help solve this problem and help you make the most of the energy you’re already using. These systems are also referred to as “Heat Transfer Kits” in New Zealand. 

 

What Is A Heat Transfer System?

Heat transfer systems move warm air from one room to another.

They use a centrifugal fan to move the air through insulated ducting which helps create a balance throughout your home. The heat transfer system automatically detects uneven temperatures and pushes warm or cool air into other rooms. HRV’s innovative centrifugal fans push air rather than blow it, for minimal noise and air disturbance. The system is easily installed and simple to operate with a touchscreen keypad, utilising set and forget technology.

Our Heat transfer system is a winter product however it is compatible with an HRV SummerKit to help circulate cooler air throughout your house in the warm months.

 

Can I Use A Heat Transfer System With My Existing Heating?

Heat Transfer makes the most of your existing heat sources by spreading their warmth into other areas of your home. It is ideal if you already use a powerful heat source, such as a fireplace or woodburner. If you don’t have a sufficiently powerful heat source, we can recommend a range of systems when you feel like it might be time to upgrade.

 

Is A Heat Transfer System The Same As A Ventilation System?

Heat transfer systems work to move warm air within your home but do not bring fresh air from outside into the house. As such they are not ventilation systems, however, our ventilation systems can be installed alongside a heat transfer system so you can enjoy the benefits of both.

  

Types Of Heat

For a heat transfer system to work well, the source room must have a heat source that can generate enough heat for multiple rooms.

Wood burners release their heat through a combination of heat radiation, which heats objects, and convection, which heats air. The amount of each varies from model to model.

Wood burners that produce mostly radiant heat make the room feel warmer than the air actually is. This makes them particularly suitable for large rooms with high ceilings and for rooms where you have poor insulation and draught issues.


Meanwhile, convective wood burners heat the air around them, which then rises to the ceiling. This means you get less heat in the bottom part of your room unless you use a ceiling fan to mix the hotter and cooler layers of air. Convective heat makes it easier to move some of the warm air to other parts of your home with a heat transfer kit.

Heat transfer kits work with a ‘large heat source’. Heat pumps do not produce enough heat to be effective for a heat transfer system, however, a ducted heat pump system can centrally heat your entire house if you lack an existing woodburner or fireplace.

Installation & Operation

Our consultants will recommend the most efficient configuration for your home and existing heating source.

Typically, the intake vent should be close to the heat source but not directly above it. More than 500mm and less than 1000mm away is optimal.

The Heat transfer system’s diffusers should be installed at opposite sides of each room to the existing HRV diffusers, and an auxiliary sensor should be installed in a wall as close as possible to the heat source. Heat transfer diffusers are not normally positioned near a window, as this can cause condensation.

Heat transfer systems are specifically designed to then transfer the rising heat from the source room and distribute it to other rooms using a network of ducts and diffusers. Heat transfer kits are a great addition to existing wood burners and fireplaces, as transferring excess heat can take the chill off cold rooms and create good airflow and warmth throughout the home. They can also reduce the likelihood of condensation and dampness.

Depending on the layout of your house, heat transfer kits can also bring warm air that has escaped upstairs back downstairs to heat other downstairs rooms. Heat rises, but sometimes we need it to go across or even down!
