I found the following post on the Green Building Advisor website. The following paragraph from the post sums up to solution:
The key to providing hot water at low flow rates with tankless water heaters is to match the combination of flow rate and temperature rise to fall within the range of the water heater's capacity. The other way is to have some amount of stored hot water (generally called a tank!) that can be used to accomodate low flow rates as well as provide for some amount of peaking capacity (which depends on the stored volume.)
I'm going to try out the Marey GAS 5L – 1.89GPM Liquid Propane Tankless Water Heater to see if the small unit works better for our needs.
