TemperZone TZT-100 - Unit Selection Guide; Unit Selection Procedure; Outdoor Pool Heating Profiles

Unit Selection
As discussed on the previous page, there are many factors that need to be taken into account when sizing a Pool
Water Heater. The minimum information you require to use this Selection Guide are:
i. Your swimming pool surface area,
ii. A prediction of the usage of your pool, and
iii. Location.
The following selection procedure is for OUTDOOR pools. For INDOOR pools, contact Temperzone for a list of additional information
required to make a more accurate unit selection.
STEP 1. Identify the Heating Prole that suits Your Intended Use & Location in Table 1 (proles A to N)
If your city is not listed, use the nearest one, or contact Temperzone Sales.
STEP 2. Determine Required Heating Capacity of MWP unit
by reading from your Pool Surface Area up to your Heating Prole , then go left to the Required Capacity (Graph 1).
STEP 3. Determine which MWP unit meets the capacity requirement
move from Required Heating Output across to the model peak capacity line (Graph 2).
STEP 4. Check other factors that may alter this recommendation up-or-down a model size
refer Notes below and exposure allowances on next page.

Note:
1. A thermal pool cover is highly recommended, if not mandatory in some Cities/States when using pool heating devices.
Heating proles for use without a pool cover is more for illustrative purposes to demonstrate heat losses without a cover,
which are signicant.
2. Longer daily operating hours of the heat pump will reduce the output capacity required to maintain pool temperature.
3. Nominal heating proles based on the following operating parameters:
- Hours of use (cover off) from 9 am to 4 pm, 7 hours.
- Nominal Heat Pump operating hours are limited to between 7 am and 5 pm. These may be subject to ltration pump
operating hours.
- 24 hour operation of heat pump (IF PERMITTED) can halve the required heat pump output capacity, eg when a 10 hour
operation of the Heat Pump appears marginal for duty, a couple extra hours operation may satisfy requirements.
4. Adjustment to heating prole requirements can be made for deviation to the tabled specications,
eg for cover off 4 hr/day, deduct 20% from required capacity; for cover off 10hr/day add 10% to required capacity.
