Are you using Mechanical Relays or Solid State Relays?
It may be worth checking the specs of the relay of the digital control. Some relays have a shorter lifespan if used with 220 volts instead of 110 volts.
The new relay I ordered has the following expectation:
10 A, 250 VAC (general use), 6,000 cycles, 40°C (excluding -G type)
10 A, 125 VAC (general use), 100,000 cycles, 40°C (excluding -E, -G types)
(http://www.mouser.com/ds/2/307/G5LE_0513-248094.pdf)
As you can see, the life expectancy, or number of on/off cycles is dramatically smaller with a 250 Volt AC device than the 125 Volt AC device.
I am thinking about switching to a Solid State Relay to avoid the mechanical wear on the device.

As far as the heating elements goes, it depends on the size of your incubator and how well it is insulated. In my little incubator, I think the 60 Watt light bulb provides too much heating, causing the temperature to go up quickly. This causes the relay to cycle quickly, about three times a minute.
The relays I purchased have a life expectancy curve that when I'm using 0.5 Amps at a 125 Volts, should give me a 1,000,000 cycles, which means the relay should last for approximately 231 days of continuous use. Yes, I know I stated 100,000 before, but that is at the rating of 5 amps. You should be able to increase the lifespan of the electrical elements of your relay by using a smaller wattage element or light bulb.
Other than that, I don't have any experience with the heating elements themselves. They look like they'll work fine.
