Holy Nova shouldn't be used at all as holy (barring some exceptions where CoH is on CD), and only when glyphed and in specific circumstances as disc.
Without the glyph 2 places to use it and you will love it. Both in Naxx.
Plague wing, the corridor between Noth and Heigan. The bats and plague monsters. Let the tank pull most of the wing, then spam Holy Nova. You will top both the DPS and Healing meters. It's fun as hell.
Military wing, Gluth fight. After a Decimate, you help kill the chow and heal your group at the same time. Once decimate is done, send your shadow fiend to gluth and regain all your mana. It's extremely helpful, but a mana hog.
Other than those two times, I never use Holy Nova in a raid.

1. Cast renew on the tank before he takes on the mob.
2. Watch for around 65 to 70 percent of the tanks HP's cast a flash heal followed by greater heal. I use quartz for latency issue to watch my heals.
3. Throw POM on the tank if the HP of others gets effected thru AOE etc.
4. The others normally casters gets renew and flash heals if necessary
5. Holy nova to proc for free heals (Thanks to Teacake and others for stressing this)
Others have touched on this but I just wanted to put in my two cents (reiterating a lot of what was said).
1. Casting renew on the tank before a pull is wasting mana. Depending on the tank you could be wasting one or two ticks of the renew, forcing you to refresh it earlier in the fight than is necessary. Cast renew after the tank takes the first hit, you will get more out of the spell that way(only slightly, but every little bit helps)
2. At 65-70% you should begin casting a greater heal. By the time the cast is complete the tank would have take another hit potentially reducing the tanks health to 55-65%. An 8k reg or 14k crit GH should bring the tank up to full, if it doesn't heal him to full, then cast flash heal. If another healer healed in that time, you can /stopcasting and cast a flash to fill them up. If you are casting the Flash heal first, you could potentially be over-healing more than necessary when your greater heal hits, especially if it crits.
3. Throw a PoM at the beginning of a fight. That way, the first hit the tank takes it will bounce to someone else. Continue throwing PoM on the tank when it is off CD. If you wait until AoE happens to cast PoM, then chances are you will have missed the damage and be forced to heal the AoE using other spells and the PoM will be sitting on a DPS who won't get hit again until the spell timer has run down.
4. Nothing wrong with this one, I'll usually cast CoH though, since normally it's multiple people getting hit. If it is only 1 dps that got hit, a simple renew should be enough, and if it's a good chunk of damage, say 10%+ add a flash heal. If it's not more than 10% health lost, there is no point in casting renew and then flash heal. Casting Flash heal after a renew would defeat the purpose of the renew, since the flash will probably be enough to heal them to full.
5. As has already been said, pretty sure you mean CoH not holy nova.
