NEW HOME AND NEW SMART-HEATING IN NORTHLAKE
This brand new 260sq/m home in Northlake, Wanaka houses one of the most low-cost and low-maintenance heating and hot water solutions we could come up with, and it’s environmentally-friendly too! Our client is a builder who invited us onto the project very early on. We set to work from the very first design stages of the build, allowing us to design the perfect heating system for the client brief, while also providing our Total Package service (includes drainage and plumbing).
OUR CLIENTS LOVED THE RESULT…
“We engaged Optum Plumbing right at the beginning of our design stage for our new home, this resulted in an efficient, energy saving and optimum heating system.”
“We like that our system combines our wetback and solar power to get the best advantages from all the systems combined”.
HERE’S HOW WE DID IT:
We designed the perfect system for our clients by installing a thermal store, radiators, underfloor heating, a wood fire with a pumped wetback system, a gas hot water heater, thermostats, a control hub, and solar (installed/supplied by another).
The wood fire provides hot water when the fire is burning, and the solar system is also able to heat water when excess power is being generated.
One really fun addition to the system was the Neohub control hub, which allows our clients to control the central heating using their smartphones.
WHAT DOES IT COST TO RUN?
Combined gas/firewood costs are approximately $350 per month during winter for both central heating and domestic hot water. The radiators and underfloor in the bathrooms/office are set to come on twice a day at a set time.
To keep the system running at its best, it is important to maintain it well. The maintenance of this system simply requires an annual service by a certified technician and occasional client maintenance.
• Technician maintenance – this is a very low maintenance system, however we recommend a technician checks the radiators are balanced and inhibitor is topped up pre-winter, this costs approximately $200 + GST.
• Client maintenance – the pressure in the system needs to be kept topped up for the system to operate. Occasionally, this may drop and need to be topped up. This is a 10-minute task, and we provide our clients with a manual specific to their system with instructions on how to do this. The filters in the Rinnai also need cleaning periodically.
