Heat Pump Buffer Tank

Do I need a buffer tank with a hydronic heat pump? Heat pump buffer tanks are recommended for heat pump hydronic systems for three key reasons:
1. Hydraulic separation for hydronic systems with heating and cooling
2. Prevent short cycling with insufficient water volume from room zoning
3. Additional thermal storage of heat produced by heat pumps using daytime solar power.

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.

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.

Underfloor heating and cooling on 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.

Hydrosol image of Stiebel Eltron buffer tanks, 100 and 1500 litre buffer tanks, larger tanks can be used as a thermal battery.

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.

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.
