Product Overview

The Raypak MVB natural gas vertical pool heater delivers 500,000 BTU/hr of input capacity for commercial pool and spa heating applications. Its compact upright design makes it a practical option for equipment rooms where floor space and access are important considerations. This configuration includes an H-bypass arrangement, pairing commercial heating capacity with a dedicated heater circulation system. Cupro-nickel heat exchanger tubing and bronze headers provide construction suited to demanding pool heating environments.

Ideal For

• Hotels, resorts, community pools, and commercial aquatic facilities requiring professionally sized heating equipment.
• Equipment-room renovations where a compact vertical heater can simplify placement.
• Pool and spa projects specifying natural gas heating with an external H-bypass.

Key Features

• 500,000 BTU/hr natural gas input for substantial pool heating demand.
• Cupro-nickel finned heat exchanger tubing with bronze headers.
• H-bypass configuration for managing heater-loop water conditions.
• Fan-assisted combustion and low-NOx design.
• Indoor or outdoor installation capability with the appropriate installation accessories.

Benefits

• Compact construction helps preserve valuable equipment-room floor space.
• Commercial heat exchanger materials support demanding service conditions when water chemistry and flow are properly maintained.
• The bypass arrangement supports appropriate heater inlet temperatures when correctly installed and adjusted.
• Installation flexibility allows the heater to be considered for both enclosed mechanical rooms and outdoor equipment areas.

Compatibility

This version is configured for natural gas. Confirm gas supply capacity, available pressure, electrical service, water flow, and venting requirements before ordering. Heater selection should account for pool surface area, desired temperature, climate, operating schedule, and heat loss.

An existing heater with a similar BTU rating does not establish direct replacement compatibility. Plumbing, vent routing, equipment access, and service clearances require separate review.

Installation Context

Installation and commissioning should be handled by a qualified commercial pool heating professional. The H-bypass must be correctly adjusted to maintain the inlet-water conditions specified by Raypak. Vent category and termination requirements depend on the installation arrangement.

What’s Included

• Raypak MVB natural gas pool heater.
• H-bypass configuration.
• Associated bronze circulation pump.

Vent termination cap and air filter are not included in the standard catalog configuration. Confirm additional job-specific accessories before purchase.

Specifications

Customer Q&A

Is 500,000 BTU the heater’s input or output rating?
It is the fuel input rating. Heat delivered to the water is lower because combustion and heat transfer are not completely efficient.

Does the H-bypass replace the pool’s filtration pump?
No. The heater circulation arrangement serves the heating system; the pool still requires a properly designed filtration and circulation system.

Can this heater be installed outdoors?
Yes, when configured with the required outdoor accessories and installed according to Raypak’s instructions.

Will it directly replace my existing commercial heater?
Compatibility requires checking gas capacity, electrical service, plumbing, venting, and clearances before installation.
