SYSTEM COMPONENTS FOR EACH CASE STUDY

MT BARKER RESIDENCE
• 500L Rotex Sanicube thermal store
• Off-grid photovoltaic solar with battery storage
• Thermalux Linea 20kW wood-fired boiler
• Rinnai Infinity gas water heater
• Underfloor heating with Neostat thermostats
• Radiator heating

BEACON POINT RESIDENCE
• 24kw Gas Boiler
• Radiators x 7
• Heatmiser Neostat Thermostats x 1
• 300L Electric Hot Water Cylinder with Thermostat
• Wood Fire
• Trench Heaters

NORTHLAKE ROAD RESIDENCE
• 16kw Kensa Ground Source Heat Pump
• Underfloor heating (7 zones)
• Heatmiser Neostat Thermostats x 7
• Radiator x 1
• Wood Fire

Additional system options:
• Domestic hot water could also be incorporated into this system, so the central heating and domestic hot water is from the same heat source.
• Heatmiser Neohub and NeoApp (smartphone application) could be installed so the client controls the system operation (e.g. turning on/off, adjusting set temperatures) from their smartphone.
• Solar PV could be installed to offset some of the electricity costs during winter (e.g. credit is built up over summer months to use over winter when the central heating pushes the electricity bill higher). As buy back rates in NZ are quite low this doesn’t always balance out depending on the clients usage.
