Small Planet Supply carries SANCO2 heat pumps and tanks, as well as TACO X-Pump Blocks and other TACO products useful for combi installation. Its easy to see why this combi system is desirable for high efficiency homes, especially when the overall goal is to save on energy spending over time. In one case study done in Nevada City there was a ~ 50% reduction in KWH used during heating season. Split System Installīy using SANCO2 in a combi system, energy usage for home heating can be greatly reduced. Lower heat loads are better suited for pairing with a SANCO2 combi system because of the relatively low heating temperature of radiant floor heating and the recovery time and duty cycle of SANCO2 systems when you take domestic hot water consumption into account.
With a high efficiency home, lower heat loads are more achievable thanks to better thermal design and highly insulated walls and windows.
When considering adding a SANCO2 combi system to your home, it is only recommended for high efficiency homes.
The basic list consists of one SANCO2 Heat Pump, at least one 83-gallon tank, two water circulation pumps, a heat exchanger, temperature sensors and controls (packaged as “TACO X-Pump Block, which is the only one approved for warranty), expansion tank, relief valve, and various check valves.

How to Configure SANCO2 Combi SystemsĬonfiguring a radiant system with a SANCO2 heat pump is achieved through good planning and the use of some key pieces of equipment. Larger heat loads may be supplemented with a second heat pump or auxiliary heat, but they latter must be carefully designed so as to not interfere with the heat pump’s efficiency. Combi systems should ideally be designed and used in climates with a design winter temperature 22F, which will ensure you don’t see a reduction in radiant floor heat output on the days when it matters most. SANCO2 heat pumps are also capable of providing hot water at very low ambient temperatures, down to -25F. It is important with this set up to note that efficiency is required that domestic hot water usage be greater than 25 gallons per day. This system should see an annual average COP of ~4 with 80F return water to the system. Since they are designed to raise main supply water from ~50F to 145F in a single pass, higher input temperatures will reduce this efficiency, which is why radiant floor with its low temperature usage is the best radiant option to pair with SANCO2.Ĭonfigured in a Combi set up such as this, a single SANCO2 heat pump design is capable of meeting heat load demands of up to ~8,000 BTU/h, while reserving the rest of its heating capacity for domestic hot water delivery. SANCO2 heat pumps offer some of the highest COPs of any heat pump water heater, and one of the crucial requirements for this is having low input temps.
