Best Residential UV Systems of 2020

Choosing an ultra violet disinfection system to treat your water can be a challenging and complicated purchase as there are many different models on the market. How do you know what system to trust with your water quality? What system is right for a small cottage, average or large home? Will the UV system I choose have the necessary output to deal with a high level of e.Coli or coliform bacteria?

I have reviewed six of the most popular UV systems available to Canadians and selected, in my opinion, the best overall system, most economical as well as the system with the most optional features. Included are the electrical draw for each system, the length and dimensions as well as the available plumbing connections. For example, if you have a tight space to install your system, you do not want a system that is too long to be able to complete the necessary maintenance, lamp changes, O-rings and quartz sleeve cleaning to ensure proper disinfection of your water.

Have you considered the water flow rates in your home or cottage when selecting a UV system? It is possible to have a system with too low of a flow rate to ensure proper bacterial disinfection of your water when multiple plumbing fixtures such as toilets, sinks, showers, dishwashers or washing machines are using water at the same time. 

The UVD320E by UVDynamics is my choice for the best economical UV System delivering a high output dose of UV Rays. It is applicable for situations with average flow rates and the cost for replacement lamps, quartz sleeves and parts are some of the most economical in the country. This is a great choice for smaller homes and cottages with all of the necessary features to provide proper disinfection of the water.

FEATURES - Economical Replacement Parts | 8 GPM Flow @ 40 mJ/cm2 | Lamp Replacement Reminder

FEATURES - Optional Sensor or Solenoid Valve | Screen Shots for System Status | Digital Lamp Counter

When selecting a Ultra Violet Disinfection System be sure to consider the water quality requirements for hardness, iron, tannin, sulphur and transmittance levels. Sediment filtration achieving five microns should precede all UV Systems. Ensure that system is sized for your water flow rater and can be easily maintained where it is installed. It is important to remember that UV Lamps and Quartz Sleeves require replacement / cleaning and most systems have these removed from the top of the unit. Generally you require the length of the UV Chamber above the system available without obstruction, to remove the lamp and sleeve properly during maintenance. 

Consult a water treatment professional if you are unsure or have questions about the proper application of any UV System.
