Electric HVAC Heating and Cooling Advice

Contact Hydrosol for electric HVAC heating and cooling advice, installation, commissioning and support

Introduction

Contact Hydrosol for electric HVAC heating and cooling advice including ventilation, hot water and pool heating. Hydrosol has the experience, qualifications and associates you need to provide quality advice and referrals. Refine your project objectives at the outset for the best outcome.

Hydrosol’s advice typically centres on:

  1. Solar power and battery storage
  2. Thermal performance of your house
  3. Cost effective electric HVAC, hot water and pool heating solutions
  4. Referrals for supply, installation and further specialised assistance

There are many new electric technologies coming onto the market. Consideration of your own preferences and budget is important too.  Therefore, we take a holistic approach to help you determine your needs and hence your HVAC system/s design.

Electric HVAC Advice

Contact us for complimentary general advice and solar power referrals or engage with our Consulting Service electric HVAC heating and cooling advice including:

  • Documenting your house as is (house type and images, thermal mass, floor plans, gas bills, etc)
  • Exploring your needs, preferences and system design/s including any opportunities to combine systems
  • Identifying and referring your solar power and solar battery requirements
  • Reviewing or estimating your heat load in order to specify the appropriate electric HVAC products:
  • Developing a plan with indicative pricing and time line that fits with your budget and needs (which could possibly run over several years)
  • Referring your HVAC plan for a final supply and install quote (which could be broken down into more than one stage)
  • Price: $390 incl GST CONTACT US

Efficient Electric House Design

Reduce HVAC design rework and project variations with some extra effort spent thinking through your needs at the outset. Experience shows that time spent on getting your design right from the start pays off with better outcomes later.

Hydrosol works with clients in many circumstances including:

  • A new building offers the greatest scope for designing an electric house with high performance
  • Renovations provide scope to fix HVAC issues with your existing house and include possibly hot water, pool and/or spa heating in the solution 
  • Going off gas is a growing area of Hydrosol’s business that requires an estimation of your current heat load from gas bills
  • Going off grid is becoming more popular thanks to new electric technologies in power generation and electric HVAC products
  • A Staged Plan makes sense if you have budget constraints even if it take several years to complete
  • Add value to your house by improving its thermal performance and upgrading to electric HVAC heating and cooling

Climate

Consider hydronic heating and cooling with solar power if you live in a cool temperate climate with cold winters and dry summers. This is the typical climate of Southern and inland Australia.

Hydronic Heat Pumps

Heat pumps provide hydronic heating and cooling in reverse cycle, ideally powered by solar. In summer, heat pumps absorb indoor heat in reverse cycle and transfer it outside.

Hydronic heat pumps transfer heat very efficiently because water is 3,300 times more effective at transferring heat than air. This is why hydronic heat pumps only need small water pipes for underfloor hydronic circuits or radiators. 

Hydronic heating and cooling using a heat pump offers these advantages:

  • Ideal for all-electric homes
  • Ideal for cool temperate climate
  • Ideal for solar power
  • Low operating costs
  • Low greenhouse emissions
  • Allergen free
  • Most comfortable radiant heat
  • Cooling in reverse cycle
  • Adds value to your house
  • Silent indoors

Air Conditioning

Air conditioners are a cost effective, all-electric means of heating & cooling using your solar power. Choose between Split, Multi-Split, VRV/VRF and Ducted systems depending on your needs, budget and house design.

Consider combining air-conditioners in bedrooms with radiant hydronic heating and reverse cycle cooling in living rooms. 

Ventilation

HRV systems reduce heat loss in winter and heat gain in summer.

Install a Heat Recovery Ventilation (HRV) system if your house is very air tight. This is most important if the thermal performance rating of your house is 7 Stars or more. Air exchange is also important to reduce air borne allergens and even viruses as we have seen with the Corona Virus in 2020.

Make your house feel fresh and airy with HRV systems.

Solar Power

Combine your heat pump or air conditioner with solar power to reduce your operating costs and greenhouse emissions.

Batteries

Install a solar battery to absorb your excess solar power.

Install a larger buffer tank with your heat pump as an additional thermal battery.

Your solar and thermal batteries will transfer stored electrical and thermal energy heating and cooling at night.

Ceiling Fans

Install ceiling fans to improve your hydronic heating and cooling system. Fans in winter mode will slowly recirculate rising heat reducing your heating costs by around 15%.

Fans in summer mode will make you feel about 4 degrees cooler. Therefore, you can increase your inside set temperature to reduce your heating costs.

Ancillary Heating

Add ancillary heating sources if possible or opportune. If you have low cost access to firewood then fireplace wetbacks are opportune. These are water jackets installed inside a firebox or around a chimney flue. They provide additional heat to the buffer tank of the heat pump. 

Passive heat radiation from north and west facing windows is a free source of ancillary heating.

Ancillary heating sources are typically variable. However, a heat pump can compensate for this by increasing or decreasing its heat load automatically.
