CONSULTANCY 

"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."

HOUSE SPECIFICS
Wanaka location, 260 sq/m floor size, 2-4 occupants
CLIENT BRIEF

Our client is a builder, who was building their own home in Northlake, Wanaka. They specifically wanted a system for their central heating and domestic hot water that would have a focus on being environmentally friendly with low running costs, low ongoing maintenance requirements and easy to run. Optum came in at the very first design stages of the build to design a heating system which fitted the clients brief. We also did the plumbing and drainage for this home, completing our total package service. 

SYSTEM COMPONENTS
> 500L Rotex Thermal Store
> Radiators
> Underfloor Heating
> Wood Fire with Pumped Wetback System
> Rinnai Gas Water Heater
> Heatmiser Neostat Thermostat
> Heatmiser NeoHub/NeoApp
> Solar PV System (installed/supplied by another)
SYSTEM OPERATION

The woodfire provides hot water while the fire is on and the PV solar will also add to the hot water when there is excess power being generated.

 

The client decided they would prefer to control the system using their smartphone, rather than the thermostats. So we installed a Neohub.

RUNNING COST

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. 

MAINTENANCE REQUIREMENTS
> 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 an manual specific to their system with instructions on how to do this. The filters in the Rinnai would also need cleaning periodically. 
A WORD FROM THE CLIENT...

"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".
