New DOE Rules for Pool Heaters & Pumps: What Arlington Owners Need to Know

The DOE has been busy. In addition to the variable-speed pump motor rules and lighting standards we've already covered, there are two more regulations that affect pool owners: new efficiency standards for pool heaters (coming in 2028) and existing standards for complete pool pumps (already in effect).

Here's what you need to know about both.

Part 1: Pool Heater Standards (Compliance: 2028)

On May 30, 2023, the DOE published a final rule establishing new energy conservation standards for consumer pool heaters. The compliance date is 2028 — five years after publication — giving manufacturers time to retool.

What Changed

The big change is the switch from Thermal Efficiency (TE) to Integrated Thermal Efficiency (TEI). The old standard only measured efficiency while the heater was actively running. The new TEI metric accounts for standby mode and off-mode energy use too — meaning heaters that waste power when idle get penalized.

Gas Pool Heaters

Gas heaters went from a flat 82% thermal efficiency requirement to a formula-based TEI standard that works out to roughly 84% for most residential units. That 2% bump doesn't sound like much, but it represents real savings over the life of the heater.

Average consumer savings: $80 over lifetime, with a 2.3-year payback period.

Most major brands (Pentair, Hayward, Raypak, Rheem) already manufacture models that meet or exceed this standard. If you bought a gas heater in the last few years, you're probably already compliant. If you're shopping for a new one, we offer professional pool heater installation services.

Electric Pool Heaters (Heat Pumps & Resistance)

This is the bigger story. For the first time ever, the DOE is regulating electric pool heaters. Both heat pump and electric resistance heaters are covered.

Heat pump pool heaters are the clear winner here. They already operate at 400-600% efficiency (they move heat rather than generating it), which far exceeds the new standard. If you have a heat pump, this rule changes nothing for you.

Electric resistance heaters are the loser. They barely meet the new standard, and the DOE's own analysis shows they're significantly more expensive to operate than heat pumps. The rule effectively discourages their use without banning them outright.

Average consumer savings for electric heaters: $1,130 over lifetime, with a 0.5-year payback — mostly driven by the shift from resistance to heat pump technology.

What This Means for You

• If your gas heater is less than 5 years old: You're fine. It almost certainly meets the new standard.
• If your gas heater is 10+ years old: When it needs replacement, the new models will be slightly more efficient. Not a huge difference, but worth considering if you're on the fence about upgrading.
• If you have an electric resistance heater: Consider replacing it with a heat pump before 2028. The energy savings are dramatic — heat pumps use 50-80% less electricity than resistance heaters. In Texas, where we heat pools for 6-8 months a year, the payback is typically 1-3 years.
• If you have a heat pump: Nothing to worry about. You're already ahead of the standard.

Part 2: Complete Pool Pump Standards (Already in Effect)

Before the 2023 motor rules we covered in our previous post, the DOE had already established standards for complete pool pump assemblies — the pump, motor, and all — back in 2017. These standards are already in effect and have been for years.

What These Standards Cover

The 2017 rule applies to Dedicated Purpose Pool Pumps (DPPPs) — complete pump units sold as a package. These standards require:

• Complete pump assemblies to meet minimum energy efficiency levels based on pump size and application
• Manufacturers to certify their pump models meet the standard
• Pumps sold as complete units (not just replacement motors) to comply

How This Connects to the 2023 Motor Rule

Here's the key: the 2017 rule covered complete pumps, but it had a loophole. When the motor itself failed — which happens before the pump housing wears out — a homeowner could replace the motor with a less efficient one, bypassing the pump standard entirely.

The 2023 motor rule closes that loophope. Now replacement motors must meet the same efficiency standards as the original pump motor. You can't downgrade when replacing a failed motor.

What This Means for You

• If you buy a new pool pump today: It already meets the 2017 standards. Any major brand (Pentair, Hayward, Jandy) sells compliant pumps.
• If your pump motor fails: The replacement must be a variable-speed motor (for 0.5 HP and above) under the 2023 rule. You can't put a cheap single-speed motor on an efficient pump body.
• If you're replacing just the motor vs. the whole pump: With variable-speed motors now required, it often makes more financial sense to replace the entire pump. A new variable-speed pump replacement will save you $500-1,000 per year in electricity compared to an old single-speed.
