BLOG

These Hydrosol BLOG articles provide information about all-electric heating, cooling, ventilation, heat pumps, air conditioners, pool and spa heaters, and solar power. They are designed to help you better understand the many opportunities and issues involved in all-electric heating and cooling.

For the best outcomes, it is important to have a house with good thermal performance. This reduces your heat load. Therefore, it reduces the size and power demand of your mechanical heating and  cooling equipment. These Hydrosol BLOG articles are centred on this theme and associated products.

All-electric Heating and Cooling

When you make the decision to go with all-electric heating and cooling, it makes sense to also consider solar power. The amount of solar power you can install, is usually determined by the size and orientation of your roof.

Hydrosol BLOG – Design

The Hydrosol BLOG articles on Design discuss heat loss. Heat loss comes from three broad areas in almost equal amounts:

  • Ceilings
  • Windows
  • Walls, floors, open windows and air gaps

Contact Hydrosol to look at your specific heat load. Explore ways to improve it. Consider your house design, preferences and budget in the process. Develop an appropriate heating and cooling solution that is right for you.

Galletti ART-U Hydronic Fan Coil

The Galletti ART-U Hydronic Fan Coil convector is becoming more popular with our all-electric heating and cooling quotes. It is designed for wall mounting in architectural spaces. This new Italian fan coil gives you efficient and effective hydronic heating and cooling when matched with an all-electric heat pump. It has a superior brushless fan motor that is very quiet. In summer, it works like a wall mounted air conditioner reducing temperature and dehumidifying your room.

Thermal image showing heat loss from slab-sides during winter, which need to be insulated to improve house heat loss.

Slab Insulation

This BLOG discusses slab insulation so that you can effectively store energy and reduce heat loss from your slab-on-ground. Insulate underneath and also the slab edges. This is very important if you have solar power because you can store excess solar energy in your insulated slab. However, a slab with no insulation creates a thermal bridge for heat to flow outside, draining away your solar energy.

Example of an Galletti ART-U fan coil convector, which provides hydronic heating and effective cooling with chilled water below they dew point.

Heat pump hydronic cooling

The Galletti ART-U can coil convector provides hydronic cooling and heating with a heat pump. The ART-U convector is designed for cooling in summer using chilled water from a reverse cycle heat pump. An internal fan draws air through its coils. Condensation is drained away outside, which gives you latent cooling as well as sensible temperature cooling. In winter, hot water from the heat pump is circulated through the convector.

Improve house heat loss

This BLOG discusses the causes and suggests steps to improve your house heat loss in winter and heat gain in summer. The causes come broadly from 3 areas, about one third each: (1) ceilings, (2) windows and (3) walls, floors and general air leaks. Your choices on what do depend firstly on whether you are building a new house, renovating an existing house or improving the thermal performance of an existing house.

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.

Improve thermal performance to effectively change a gas boiler to heat pump

Replace your gas boiler with a heat pump

Replace your gas boiler with a heat pump for heating and cooling. Other benefits include much lower heating and cooling bills by using your own solar power, less greenhouse emissions, adding value to your home, longer life and safer.

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.

Heat pump thermal battery

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.

Cool Temperate Zone Heating

A cool temperate climate zone such as Victoria is well suited to hydronic heat pumps. This is an efficient and effective way of heating and cooling if your home is well insulated. It will give you low operating costs and can be largely powered by your solar panels. Cool Temperate zones have: low humidity,
high diurnal range (temperature swings), cold to very cold winters and hot dry summers.

How a hot water heat pump works

Heat Pump Water Heater

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.
