Frequently Asked Questions
Does this unit require a temperature and pressure (T&P) relief valve?
While the Eemax HomeAdvantage II series is certified to UL 499 standards, specific jurisdictions—such as the Commonwealth of Massachusetts and the State of Kentucky—strictly require a pressure relief valve for installation. Always verify local plumbing and electrical codes in your area before beginning installation.
Can the HA036240 be mounted horizontally or upside down?
No. This water heater is explicitly designed to be mounted in an upright position with the 3/4" NPT brass inlet and outlet connections positioned at the bottom of the unit. Altering this orientation can lead to internal system failure or element damage.
What are the dedicated electrical infrastructure requirements for this 36kW unit?
The HA036240 requires 240V single-phase power and draws a maximum total amperage of 150 Amps. Your home's electrical panel must support four dedicated 40 Amp double-pole circuit breakers and four separate sets of 8 AWG copper wire with 75°C insulation. A minimum household electrical service panel of 300 Amps is recommended.
Can I solder copper pipes directly onto the heater fittings?
No. Never solder any plumbing connections while they are physically attached to the water heater. The extreme heat generated from a torch will permanently melt the internal flow sensor and void the manufacturer warranty. Utilize flexible hoses or solder adapters before making your final connection.
Why We Like It:
The Eemax HA036240 is an excellent whole-house option because it brings 36kW of heavy-duty heating capacity into a space-saving footprint, resolving the footprint restrictions of bulky storage tanks. Its multi-chamber copper heat exchanger transfers heat rapidly while resisting hard water scaling. When preparing your project site, ensure your electrical service panel has the necessary 150 Amp capacity to supply four independent 40 Amp breakers. To ensure system longevity, remember to fully purge all remaining air pockets from your hot water plumbing lines for a couple of minutes before engaging the electrical breakers to prevent dry-firing your immersion elements.
