We're about to explore Califont flow rates. Don't worry, it's more straightforward than it seems, and I'm here to guide you.

Why bother with flow rates and Califonts? You can't have a Califont without understanding flow rates - they help determine your household's hot water needs. It's the amount of water your Califont can heat in a minute.

So, how are flow rates measured and matched to Califonts?

Understanding the Relationship Between Flow Rate and Water Temperature

So, you've felt the jarring sensation of sudden hot and cold water in your shower? It points to the balance between water flow rate and temperature.

Your Califont water heater works best under certain conditions. The flow rate, or the volume of water it processes, affects how well it heats the water. It's a delicate balance of stable heating efficiency and variable water flow.

The optimal flow rate for each Califont is its 'Goldilocks zone,' where it operates most efficiently for constant and comfortable water temperature. Go above or below, and you risk cold or hot water.

Choosing the Right Califont: Matching Flow Rate to Your Needs

Identifying the right Califont size depends on the number of outlets you have, including showers, taps, and appliances requiring hot water. For instance, should you need to use the shower, the dishwasher, and a tap simultaneously, a Califont with a higher flow rate would be required than using only one tap. However, you need also to match that with the feed flow rate.

Wondering about the standard flow rates for everyday items like showerheads and faucets?

Household ItemFlow Rate (LPM)
Standard Showerhead9-12
Water-Saving Showerhead7-9
Bathroom Faucet4-6
Kitchen Faucet6-9
Washing Machine15-25

Why are all these figures important? 

When matching with a Califont, you should know about expected usage, as it helps in calculating whether the Califont can provide enough hot water for your requirements.

Here's a comparison table:

Califont SizeFlow Rate (Litres per Minute)Common Use
Mini5 L/mCaravan or Motorhome.
Small (e.g., 16L)16 L/mSuitable for smaller homes with one shower and a few taps.
Medium (e.g., 20L)20 L/mExcellent choice for medium-sized homes with up to two showers and multiple taps.
Large (e.g., 26L)26 L/mPerfect for larger homes where hot water is necessary in multiple places at once.

How to Measure the Flow Rate Going into your Califont

Let's go ahead and measure your Califont's flow rate.

  1. Prepare your tools: You will need a bucket and a timer. Ensure the bucket has clear measures and the timer accurately counts seconds.
  2. Pre-settings: Before turning on your Califont, ensure all other water appliances are turned off for accurate measurements.
  3. Begin measurements: Turn on your Califont and let the water run into the bucket for a minute. It is essential to time this accurately.
  4. Evaluation: Now, observe the amount of water in the bucket in litres. This is your Califont's flow rate in litres per minute (LPM).

And that's it! In four easy steps, you have measured your Califont's flow rate.

What do I do if I have too much incoming flow rate?

You might need to reduce the feed. This can be done with a pressure-reducing valve or an adjustable tap or ball valve just before the Califont. The adjustable tap option will let you set the throughput to be optimal for your Califont.

Summary: Deciding on a Califont Flow Rate 

Figuring out the best Califont flow rate might sound like a matter of Mastermind level, but trust me, it's simpler than you'd think. Put your genius cap on, and let's call on Sherlock Holmes of the plumbing world. Here are the key steps involved: 

  • Decide on your usage level (how much water do you need)
  • Decide on your feed flow rate (how much water you have)
  • If needed adjust the incoming flow rate
