Due to the history of the company you see Jandy pool heaters sold under a number of names. I have seen them under Laars Pool Heaters, Teledyne Laars Pool Heaters and Jandy Pool Heaters. I have made an attempt to very briefly cover the history below.
The originial company was Laars Engineers formed in 1948. It was bought by Teledyne in the mid 1960s and became Teledyne Laars. In 1996 Teledyne bought Jandy Industries and started marketing their pool heaters under that name (but sometimes including the Laars name). Shortly afterwards the business was divided into 3 with Jandy having the residential pool business and Laars Heating Systems the business side. In 2007 Jandy merged with Zodiac Marine to create Zodiac Pool Products and create ?a major global supplier of pool equipment?. In the current Zodiac Brochure two of their three heaters are branded Jandy and one Zodiac (but the name Laars still often appears when these are sold).??? ?
The current range of Jandy pool heaters comprises:
Jandy Hi-E2 (although officially this is the Zodiac Hi-E2) ? A top quality 350k gas pool heater for residential or commercial applications (it is ASME certified). The energy efficiency is an incredible 95% (and it is low NOx) putting it well ahead of other gas heaters. It is designed for long life and low maintenance and built using top quality materials. The negative with this heater is the cost as it is about triple the price of other Jandy pool heaters.
Jandy LXi ? A range of gas heaters from 250k ? 400k BTU/hr (models for natural gas and propane) with an energy efficiency of 88%. In addition they have low NOx emissions meeting all requirements in this respect. These heaters have a feature rich control panel which can be mounted remotely.
Jandy Legacy ? Ranging from 125 ? 400k BTU these gas pool heaters are available in both electronic and millivolt versions. They are 83% efficient and make no claim to be low NOx. The legacy heaters have a number of advanced features, are designed to be reliable and are relatively inexpensive, making then good value for money.
Jandy Heat Pump ? There are 3 heat pumps in the range at 100, 115 and 131 BTU. The two higher capacity models have a chiller/defrost option that enables the heat pumps to function in low temperatures and also cool the pool when necessary. All models feature a standard titanium heat exchanger (with lifetime warranty against corrosion). The heat pumps require a 40amp electricity supply.
Which should you choose? There are two key factors to consider. How often will you use the pool heater and will you consider a higher purchase price in anticipation of savings in the years ahead? If you want to heat the pool all the time during the season then a heat pump will best meet your needs even though they are not cheap to buy. If you do not heat your pool constantly then a gas heater will get it up to temperature faster and the difference in running costs may be offset by the cheaper price. In this case the Hi-E2, good though it is, would seem to be rather over the top leaving the choice between the LXi and the Legacy. If NOx emissions are an issue in your location then it will have to be the LXi but if not the legacy would seem to be the best buy. Of course if you need a millivolt heater then the Legacy is the only option from Jandy pool heaters.
