These Hydrosol BLOG articles provide information about all-electric heating, cooling, ventilation (HVAC), domestic hot water and pool heating. Gain a better understanding of the issues and opportunities around electric heat pumps, ventilators, air conditioners and solar power.

For the best outcomes, it is important to have a house with good thermal performance. This reduces your heat load and therefore reduces the capital cost and power demand from your HVAC equipment. These BLOG articles are centred on this theme along with associated products and services.

Electric Heating and Cooling

Consider solar power and the thermal performance of your house when you make the decision to go with electric heating and cooling. Design for solar power with shading, roof space and orientation in mind.

Hydrosol is happy to make a referral to G-Store to look at your specific solar power needs, contact us

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.

Fix Green Pool Water

Fix green pool water because it is likely caused by algae, which is dangerous to your family and friends and will harm your pool equipment. Green pool water is a visual clue that your pool water may be contaminated depending on the specific cause. It reflects significant growth of micro-organisms in your pool water. Swimming pools have restricted water volume and continually pick up micro-organisms that have nowhere to go. If left untreated, they will proliferate and turn your pool water green. Apart from algae, these micro-organisms also include bacteria, fungi and germs.

Heat Pump Pool Heating

Extend your swimming season by heating your pool sustainably. This is achieved naturally from direct sunlight and also from heating systems. Due to concerns of global warming and the rising cost of gas, solar systems and electric heat pumps powered by solar panels have become increasingly popular. The main advantage of heat pump pool heating over a solar system is that it doesn’t take up roof space that can be otherwise used for solar panels, which generate power for other household needs apart from pool heating.

Hydrosol image of one of the Heat Pump Hydronic Testimonials from the many electric heating and cooling projects done over the years.

Heat Pump Hydronic Testimonials

These heat pump hydronic testimonials set out feedback from clients about their electric heating and cooling systems. Hydrosol has been involved with many such projects over the years developing knowledge and experience along the way. Therefore, contact us about what is best for your electric HVAC project. We are often asked about the efficiency and effectiveness of underfloor hydronic area cooling and some of the following testimonials speak to that. For example: ‘’In summer, the house the slab with the cooling keeps the ground floor cool and at a max of 21 C. On the hottest days we run the fans to circulate the cool air. That’s all that’s required.’’ etc.

Hydrosol image of Galletti ART-U Hydronic Fan Coil, brushed aluminium, for heating and cooling

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.

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.
