Heating and Cooling Systems Adding Value to your Home

Heating and Cooling Systems add Value to your Home

This BLOG discusses all-electric heating and cooling systems adding value to your home. It discusses mandatory energy ratings that have been in force in the UK and Europe for more than a decade, slowly catching on in Australia starting with the ACT. The justification for all-electric heating and cooling includes: a) lower running costs with solar power, b) adding value to your home and c) reducing Greenhouse emissions.

Factors affecting Heating, Ventilation and Cooling Design

Factors Affecting HVAC Design

Heating, Ventilation and Cooling (HVAC) Design starts with thinking through your needs. Good building design has low heating and cooling requirements. This enables all-electric solutions with energy efficient appliances such as inverter heat pumps and air conditioners. These appliances can be largely powered by solar panels. The thermal energy can be stored in the mass inside your home during the day and released at night.

Underfloor heating and cooling suspended floors

You can enjoy underfloor heating and cooling if you are renovating or building with suspended floors. Use a heat pump as the heat source to have reverse cycle cooling in summer as well. This will absorb heat from your home and expel it outside in reverse cycle mode. You can apply most types of floor coverings over your underfloor heating circuits including tiles timber boards and loose weave carpet.

Thermal Battery

Heat pump thermal battery maximises your solar power

Consider adding a larger heat pump buffer tank or thermal battery to increase the internal mass of your home for greater thermal storage. This will help moderate the extremes of your indoor temperatures, reduce your power consumption for heating and cooling and maximise your solar power during the day.

How a hot water heat pump works

Heat Pump Water Heaters

Heat Pump Water Heaters use about one quarter of the power of an electric element water heater. They are an ideal appliance to use with your solar power because you can time them to run during the day. They act like a battery storing thermal energy to use 24/7.

heat recovery ventilation

Reduce Heat Loss and Improve Air Quality with HRV Ventilation

Reduce heat loss and running costs, and improve air quality with Heat Recovery Ventilation (HRV). This BLOG explores HRV and ERV ventilation systems. Homes built years ago were not designed for efficiency and so they leaked air everywhere. Modern homes with 6+ Star rating are much more air tight and require ventilation systems to keep a fresh feel inside without needing open windows in winter and summer. Air leaks and open windows can account for a quarter of your energy costs.

energy efficient home case study

Heat Pump Hydronic Heating

Heat pumps use water to transfer heat to your home in winter from the outside air and reverse this process in summer to keep your home cool. Water is 3300 times more capable of transferring heat than air so you don’t need large air ducts with heat pumps.
