    Back Heating/Cooling

    When should I use a heater?

    When your room temperature falls below 18 degrees is recommended.

    Can a single high wall unit heat multiple rooms in the house?

    No, the heat pump should only ever be sized for the room it is in so installing in a hallway to service bedrooms is not recommended.

    What is Auto Defrost Cycle?

    Defrost Cycle occurs in cold conditions during heating mode; when the outside ambient temperature is very cold (near 0°C or below) the moisture in the outside air freezes on the outdoor unit’s coil as the fan blows air across it. The Defrost cycle simply recognises that ice has formed, or has begun to form, on the outdoor unit coil and starts to automatically de-ice’s the outdoor coil.

    Defrost mode is needed as any ice build-up on the outside heat coil will reduce the airflow across it, effecting efficiency and operation of the heat pump.

    When the heat pump goes to defrost mode, you’ll notice the indoor unit will stop heating, the indoor fan will stop or slow right down, the indoor louvers may change position and depending on the model there may be a blinking light on the indoor unit. At the same time the outdoor unit fan may stop running, though the outdoor compressor will continue to run.

    NOTE: It is important not to turn off the unit or change any settings on the remote before the defrost cycle has ended; if the unit is restarted prematurely it will resume the cycle and cause delays in completing the defrost function.

    Why are heat pumps more efficient than traditional heaters?

    Heat pumps move available heat from one place to another. An outdoor unit absorbs warmth from the surrounding air and transfers it into your home. By utilising a compression cycle, heat pumps can produce 4kW of heat energy whilst only draw in 1kW of electricity.

    Where in my home should I put my heat pump?

    We recommend the lounge and living areas as the primary place for heat pumps. There are also smaller options available for bedroom heating and cooling.

    Note: The heat pump should only ever be sized for the room it is in so installing in a hallway to service bedrooms is not recommended. Over or under sizing your heat pump can result in premature failure of certain components in your unit, it can also be less energy efficient, overshoot temperatures causing uncomfortable temperature conditions.

    How big do I need my heat pump to be?

    We supply a range of heat pumps to suit your needs and recommend a free home assessment to specify the best heat pump for you. As a rule of thumb, rooms that are small and well insulated only need a small heat pump and large rooms with lots of windows/external walls will need a larger heat pump.

    HRV use the standard best practice guidelines to suitably size the heat pump based on the age, insulation properties and size of the rooms you are needing to service.

    Can I use my heat pump to cool?

    Yes - a heat pump also work as an air conditioner so is a great option to cool your home.

    Will my heat pump help to dry the home?

    We recommend an HRV ventilation system for drying the home and a heat pump for heating and cooling. These two products work well together because a drier home is easier and more energy efficient to heat.

    Are heat pumps noisy?

    The internal wall mounted unit has a fan which is designed to be as quiet as possible during operation.

    Why choose HRV?

    HRV provides the correct product specification for your home, installation, and after sales service. HRV provide quality products from trusted heat pump brands like Panasonic.

    How do I control my heat pump?

    A remote is supplied with the product, along with comprehensive guide on usage. Your friendly HRV installer can show you how to use the heat pump. You also have the option of additional wifi control from your smartphone or tablet device. Call 0800 HRV 123 if you have any questions about how to operate any HRV product.

    What is a Thermostat?

    A thermostat turns an electric heater ON if the room temperature is below the set temperature. A thermostat turns an electric heater OFF if the room temperature is above the set temperature.

    What is a Thermostatically controlled heater?

    All HRV heaters have a Thermostat. The heater will have a variable thermostat so you can control the set temperature (the max temperature of the room).

    Digital display can be easy to use. Set the temperature between 18 and 21, turn the power on, and the heater will work to keep the room at the set temperature.

    Manual dials 1 to 5 should be avoided as they can be confusing for people to operate.

    What are the benefits of using a 7 day timer?

    You can easily programme the heater to turn on and off when you are in the home. This will significanly reduce heater power consumption as you are forcing the heater to turn off when you are not there.

    How many heaters do I need for an average three bedroom house?

    HRV can pop around to your house to provide a free home assessment and discuss your heating requirements, as this can significantly vary depending on building design.

    How much will it cost to install a whole home heating solution for a 3 bedroom Home?

    Every home is different to please ask for a free home assessment.

    Does a higher KW heater use more electricity?

    Yes, but the higher KW heater will heat the room up quicker to the set temperature, then turn off. How well the room is insulated will affect how long the heater is off for. The heater will automaticlly turn back on when the room temperature falls below the thermostat temperature.

    A higher KW heater will keep you warm even on the coldest evenings.

    Do I need a heater if I already have a heat pump?

    A high-wall heat pump is designed to heat the room it is installed in, it's not a whole home heating appliance. If the heat pump is in the living area, heaters are ideal for providing heat in smaller bedrooms.
