Product Overview

The Hayward HP21405T HeatPro MCHX Series Heat Pump is built for pool owners and service professionals who want higher-capacity in-ground pool heating from a current Hayward heat pump platform. With its 140,000 BTU output and heat-only configuration, it is designed for users focused on extending swim season and maintaining warmer pool temperatures without moving to a heat-and-cool model. Hayward’s current materials frame this unit around the newer MCHX platform and its microchannel design.

What makes this model especially appealing is the combination of capacity and updated platform positioning. Hayward’s official listing highlights the current HeatPro MCHX Series branding, while broader product references and retailers consistently present HP21405T as the 140K BTU heat-only option. For listing purposes, the strongest version is to identify it as a HeatPro MCHX Series heat pump rather than using a more generic HeatPro title alone.

Frequently Asked Questions

What part number is this pool heater?

This item is supplied under part number HP21405T. Match that number against your equipment's parts diagram before ordering.

Does the BTU rating have to match my old heater?

The BTU rating should match or exceed your previous heater. Undersizing means the pool never reaches temperature on cold days; oversizing costs more up front but heats faster and cycles less.

Can this run on propane instead of natural gas?

No. Gas pool heaters are built for one fuel and require a manufacturer conversion kit to change. Check the data plate on your existing unit and order the matching fuel type.

What size heater do I need for my pool?

A common rule is 1 BTU per gallon as a minimum, increased for windy sites, uncovered pools, or cold climates. A 20,000 gallon pool typically starts at 250,000 BTU.

Do I need a professional to install a pool heater?

Gas heaters involve gas line sizing, venting and electrical connections, and most jurisdictions require a licensed installer plus a permit. Improper installation voids the manufacturer warranty.

How do I confirm this part fits my equipment?

Check the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.

How quickly does this ship?

In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.

Can I return it if I ordered the wrong part?

Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.

Is this covered by a warranty?

Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
