A detailed comparison between solar thermal and solar PV.

An Apricus ETC30 collector has 2kW peak output for 4.4m² collector, operating at 60% – 70% efficiency at domestic hot water temperatures.  This compares to 2kWp photovoltaic (PV) solar system covering 13m² of roof and operating at up to 20%

Reducing Carbon Emissions in Buildings – Carbon Neutral Government Programmes

Apricus Eco Hot Water & Heating is helping organisations to find ways to meet the new requirements under the Building for Climate Change programme, Transforming Operational Efficiency framework and the Government Carbon Neutral Programme.   We are providing technical &

Why using wood pellets is better than burning fossil fuels

Why using wood pellets is better than burning fossil fuels One of the best modern alternatives to gas, oil and coal fired central heating and hot water systems are wood pellet or biomass boilers. A pellet boiler is a long-term,

Energy performance comparison for hot water heat pumps and solar hot water.

It’s difficult to compare COPs between heat pumps and solar hot water systems because it depends on when you are measuring them.  A solar hot water system using only 30W for the pump will be returning up to 2kW of

Sustainable Heating Technologies for CIBSE

The Chartered Institution of Building Services Engineers (‘CIBSE’) bring to you three online lunch time sessions that will provide a comprehensive overview of wood pellet fuel and boiler technology for the replacement of fossil fuel boilers in commercial applications. The

Why harnessing CO2 makes better sense than burning fossil fuels

The energy needed to heat hot water has to come from somewhere. The more renewable the energy is, the less greenhouse gas emissions are created. Plus the more efficient the technology the less energy that is needed. Isn’t carbon bad?

Particulates and Greenhouse Gas Emissions

Pellet Boilers from Apricus Eco Hot Water & Heating In New Zealand, wood pellet fuel is 100% made from waste sawdust and wood shavings, bi-products of the timber milling industry in this country.  There are minimal alternative uses for these

Low carbon hot water systems to replace gas and coal in commercial businesses

We can all play a role in developing a more energy-efficient economy using lower carbon, cleaner technologies in our buildings. By focusing on decarbonising energy our government is starting to deliver on the commitments we made in the Zero Carbon

Can I replace an instantaneous gas hot water system with a CO2 heat pump system?

Replacing your instantaneous gas hot water system with a C02 heat pump system is easy.  Making the change has many benefits including ongoing energy savings and a reduction in your carbon footprint, by using highly renewable NZ electricity combined with

FAQs about CO₂ Hot Water Heat Pumps

What is a CO₂ heat pump? Heat pump water heaters absorb warmth from the air, amplify it and transfer it to heat water. Therefore, they are also referred to as ‘air-source heat pumps’. Heat pumps use electricity to operate the

What is the difference between flat plate and evacuated tube solar hot water collectors?

Generally, flat plate systems are cheaper, but there are many good reasons to pay a little bit more for evacuated tube solar hot water collectors. See below: They capture more of the sun’s energy at a given time because they

$28 million fund for Renewable Energy in Maori and social housing

The Ministry of Business & Innovation (MBIE) are asking for people to get in touch for a share of $28 million for Renewable Energy and Decarbonisation in Maori housing. Apricus can partner with you to serve your communities and improve
