  • When upgrading a pool heating system, often there are site restrictions, an onsite build helps address these
  • 1# We build the unit in-house and complete all in-house testing.
  • 2# Disassemble unit into major components, keeping the integrity of the heat pump
  • 3# Deliver unit components to project site. Allows the carrying of components into location
  • 4# Rebuild unit in place.
  • 5# Re-test unit and commission for use.

COIL UPGRADE: Baked Enamel Coated Coils:

  • Extremely durable coating that will significantly increase the lifespan of your heat pump.
  • Helps to prevent or significantly reduce coil deterioration especially in highly corrosive environments.
  • Deep Set coils used to increase surface area whilst minimising space.

Toyesi’s Unique Water Balance Valve & COP Kit – An Efficiency Maximising Solution

  • Most heat pumps in the market you simply plumb the water pipes to the unit and turn on the water.
  • However too much or too little water flow will affect your heat pumps performance and heating capacity.
  • If too much water goes through a heat pump the water does not stay in the heat exchanger long enough to pick up the heat required to bring the pool to your desired levels.
  • This will cause you to unnecessarily run the heat pump for extended periods of time to make up for the inefficiencies caused by the low internal pressures and low water flow.
  • Too small amount of water flow will also cause your heat pump to run inefficient and drive up internal pressures, potentially to critically high levels.
  • These high levels can cause refrigerant issues such as burnt refrigerant, leaks and other known issues.
  • Variable speed water pumps can also have a negative effect on heat pumps by acerbate these issues.

  • Winter Verses Summer: Did you know that the amount of water passing through a heat pumps’ heat exchanger will also vary in correlation with the ambient temperature.
  • Most heat pumps do not address this issue causing either too much or too little water flow through the heat pump’s heat exchanger.
  • Most heat pumps address these seasonal issues by allocating a water flow rate mid-way between the two in the attempt to minimise the water flow impact.
  • Or set the unit for maximum flow rate and let you wary about excess running costs.
  • Toyesi’s Unique Water Balance Valves are used to adjust water flow levels through the heat exchanger, allowing for excess waterflow to safely bypass the heat pump and delving the correct amount of water through the heat pump for optimum heat pump performance.
  • This means you can set your water pump up and not wary about any variable speeds of flow.
  • You can adjust the value as often or as little as you like, but we recommend a minimum of twice a year to allow for maximum efficiencies during the cooler winter or hotter summer month
