Raypak AVIA HD with NiTek Gas Pool & Spa Heater – Supplied & Professionally Installed by 4Most Energy

The Raypak AVIA HD with NiTek is a next-generation residential pool and spa heater designed for powerful performance, advanced durability, and smart system integration. Featuring Raypak’s proprietary NiTek heat exchanger technology, this heater offers significantly improved resistance to erosion and corrosion compared with traditional copper or cupronickel heat exchangers, helping extend system lifespan in chemically treated or saltwater pool environments.

The AVIA series delivers high heating capacity with an 84% thermal efficiency rating, providing fast heat-up times and stable water temperatures for residential pools and spas. The unit includes integrated Wi-Fi connectivity and Raymote™ mobile controls, allowing homeowners to monitor temperature, manage scheduling, and receive system alerts remotely through their smartphone.

Professional installation is critical to ensure optimal heater performance, safety, and longevity. Pool heater installation requires proper gas line sizing, correct water flow configuration, and compliant venting installation when installed indoors. The AVIA heater supports both Category I and Category III venting systems and can be installed in indoor or outdoor configurations depending on site conditions.

For homeowners in Toronto and across the GTA, correct system sizing is essential to ensure the heater matches the pool volume and heating requirements. Oversized or undersized equipment can lead to inefficient operation and increased operating costs. A licensed gas technician in Ontario must verify gas pressure, combustion performance, and water flow during commissioning.

4Most Energy provides professional pool heater installation in Toronto and the GTA, ensuring the Raypak AVIA system is installed according to manufacturer specifications and Ontario gas code requirements.

We had a great experience with Rey and his team during our new Rinnai boiler installation. The technicians did an amazing job and worked efficiently. The technician Sam was knowledgeable, professional, and respectful throughout the installation. He took the time to answer all my questions and made sure everything was properly checked before finishing the job.

They arrived on time and completed the boiler installation on schedule.

We are very happy with the service and would definitely recommend them to anyone looking for reliable and professional HVAC service.

Thanks.

I was very pleased with the competitive pricing I got specifically from 4most energy. I contacted many companies to get their best quote. Sometimes there are even daughter or sister companies that will give you better quotes than the parent companies. It's best to check around for the identical product with installation from many companies. I was also pleased with the installers. They did have to cut away some insulation to install the Rinnai RX199 on the outside wall the house. Not sure if they should have tried replacing that insulation afterwards, but won't complain about the job they did because I think I got the best price on the market after getting quotes from about a dozen companies.

We recently had a Navien Combi boiler installed by 4Most Energy and had a great experience from start to finish. Rey was our sales representative and Sam was our technician, and both were excellent to work with.

They arrived on time, the installation was fast and efficient, and everyone was friendly and professional throughout the process. Sam did a great job with the installation, and everything is working perfectly.

We’re also very happy with the Navien Combi boiler itself. Overall, we couldn’t be happier with the service, the installation, and the product. We would definitely recommend 4Most Energy.

I contacted 4Most Energy to replace my 14 year old AC unit. Their intake process was smooth. They provided a reasonable quote the same day. The installation of the new AC unit was scheduled and the service provided by Farzad and his associate was completed within a reasonable time. They did a great job on the installation, hauled away the old equipment, and left the job site (both indoors and outdoors) in good condition. I would not hesitate to recommend 4Most Energy for your heating and cooling needs.

Great job Rey, Sam and team! My tankless water heater was broken for two months and after getting the run around from Enercare and Reliance, I decided on purchasing a Navien from 4Most Energy and they did a great job explaining the process and installing it the next day. Thank you for the top notch service!
